2014-12-08support/scripts/dependencies.sh: cleanup the output of the 32 bits gcc testJens Stimpfle
The screen is cluttered when we build for 32 bit target and 32 bit gcc is missing. ~/buildroot$ make [...] /usr/bin/ld: cannot find crt1.o: No such file or directory /usr/bin/ld: cannot find crti.o: No such file or directory /usr/bin/ld: skipping incompatible /usr/lib/gcc/x86_64-linux-gnu/4.9/libgcc.a when searching for -lgcc /usr/bin/ld: cannot find -lgcc /usr/bin/ld: skipping incompatible /usr/lib/gcc/x86_64-linux-gnu/4.9/libgcc_s.so when searching for -lgcc_s /usr/bin/ld: cannot find -lgcc_s /usr/bin/ld: cannot find -lc /usr/bin/ld: skipping incompatible /usr/lib/gcc/x86_64-linux-gnu/4.9/libgcc.a when searching for -lgcc /usr/bin/ld: cannot find -lgcc /usr/bin/ld: skipping incompatible /usr/lib/gcc/x86_64-linux-gnu/4.9/libgcc_s.so when searching for -lgcc_s /usr/bin/ld: cannot find -lgcc_s /usr/bin/ld: cannot find crtn.o: No such file or directory collect2: error: ld returned 1 exit status [...] Your Buildroot configuration needs a compiler capable of building 32 bits binaries. The final note is enough, and adding 2>/dev/null to the gcc test invocation is also more consistent with the rest of the script. The patch makes the '/usr/bin/ld:' and 'collect2:' lines go away.

2014-11-30infra: do not append an empty LD_LIBRARY_PATHYann E. MORIN
When we set LD_LIBRARY_PATH when building our host tools, we append any pre-existing value to our custom path: LD_LIBRARY_PATH="$(HOST_DIR)/usr/lib:$(LD_LIBRARY_PATH)" But then if LD_LIBRARY_PATH was previously empty, we end up with an LD_LIBRARY_PATH that ends with a colon. Also, when we check that an existing LD_LIBRARY_PATH does not contain CWD, we previously did not look for a zero-length prefix. Since 'man ld.so' says of LD_LIBRARY_PATH: A colon-separated list of directories in which to search for ELF libraries at execution-time. Similar to the PATH environment variable. And POSIX states about PATH: A zero-length prefix is a legacy feature that indicates the current working directory. And bash also recognises a zero-length prefix to search in CWD: A zero-length (null) directory name in the value of PATH indicates the current directory. We may thus end up on a system where a zero-length prefix in LD_LIBRARY_PATH is interpreted as CWD. Do not append the previous LD_LIBRARY_PATH if it was empty, and check for a zero-length prefix when checking dependencies. Signed-off-by: "Yann E.

2014-10-07.mk files: bulk aligment and whitespace cleanup of assignmentsThomas De Schampheleire
The Buildroot coding style defines one space around make assignments and does not align the assignment symbols. This patch does a bulk fix of offending packages. The package infrastructures (or more in general assignments to calculated variable names, like $(2)_FOO) are not touched. Alignment of line continuation characters (\) is kept as-is. The sed command used to do this replacement is: find * -name "*.mk" | xargs sed -i \ -e 's#^\([A-Z0-9a-z_]\+\)\s*\([?:+]\?=\)\s*$#\1 \2#' -e 's#^\([A-Z0-9a-z_]\+\)\s*\([?:+]\?=\)\s*\([^\\]\+\)$#\1 \2 \3#' -e 's#^\([A-Z0-9a-z_]\+\)\s*\([?:+]\?=\)\s*\([^\\ \t]\+\s*\\\)\s*$#\1 \2 \3#' -e 's#^\([A-Z0-9a-z_]\+\)\s*\([?:+]\?=\)\(\s*\\\)#\1 \2\3#' Brief explanation of this command: ^\([A-Z0-9a-z_]\+\) a regular variable at the beginning of the line \([?:+]\?=\) any assignment character =, :=, ?=, += \([^\\]\+\) any string not containing a line continuation \([^\\ \t]\+\s*\\\) string, optional whitespace, followed by a line continuation character \(\s*\\\) optional whitespace, followed by a line continuation character Hence, the first subexpression handles empty assignments, the second handles regular assignments, the third handles regular assignments with line continuation, and the fourth empty assignments with line continuation. This expression was tested on following test text: (initial tab not included) FOO = spaces before FOO = spaces before and after FOO = tab before FOO = tab and spaces before FOO = tab after FOO = tab and spaces after FOO = spaces and tab after FOO = \ FOO = bar \ FOO = bar space \ FOO = \ GENIMAGE_DEPENDENCIES = host-pkgconf libconfuse FOO += spaces before FOO ?= spaces before and after FOO := FOO = FOO = FOO = FOO = $(MAKE1) CROSS_COMPILE=$(TARGET_CROSS) -C AT91BOOTSTRAP3_DEFCONFIG = \ AXEL_DISABLE_I18N=--i18n=0 After this bulk change, following manual fixups were done: - fix line continuation alignment in cegui06 and spice (the sed expression leaves the number of whitespace between the value and line continuation character intact, but the whitespace before that could have changed, causing misalignment. - qt5base was reverted, as this package uses extensive alignment which actually makes the code more readable. Finally, the end result was manually reviewed. Signed-off-by: Thomas De Schampheleire <thomas.de.schampheleire@gmail.com> Cc: Yann E.

2014-02-19infra: Introduce BR2_HOST_NEEDS_JAVAMaxime Hadjinlian
XBMC needs Java on the host in order to build, because it uses a code-generator which is built in two phases: In the first phase SWIG is used to parse C++ header files that define the API. SWIG outputs an XML file that contains a complete description of the structure of the API. In the second phase, the XML file is ingested by a Groovy (Java) program that then creates C++ code that forms the bridge to the scripting language (Python). The second phase is why we need java on the host. You can learn more at the XBMC's wiki: http://wiki.xbmc.org/index.php?title=Codegeneration#How_it_works In order to check that, this patch introduce this mechanism in dependencies.sh, and it also defines the variable in Config.in [Peter: fix error message] Signed-off-by: Maxime Hadjinlian <maxime.hadjinlian@gmail.com> Signed-off-by: Peter Korsgaard <peter@korsgaard.com>

Currently this test does not set any output for the compiler which causes a stray a.out to be create outside the output directory.

2014-01-22dependencies.sh: stop mixing echo and printf (use echo)Bjørn Forsman

2014-01-21Prefer 'printf' over 'echo -e' (for portability)Bjørn Forsman
support/dependencies/dependencies.sh uses #!/bin/sh shebang. It is not guaranteed that /bin/sh provides an 'echo' implementation that understands the '-e' flag (interpret backslash escape chars). For example, dash doesn't. 'printf' is more portable (it must interpret backslash escape chars, according to POSIX), so use that. NOTE: Before the previous commit, the dependencies.sh script used /bin/echo instead of the shell built-in. That's probably why this hasn't come up before.

2013-12-01core: add BR2_HOSTARCH_NEEDS_IA32_COMPILER optionThomas Petazzoni
Some bootloaders (such as Grub) need to be built for x86 (i.e IA32) even if the target architecture is x86-64. However, when the target architecture is x86-64, the cross-compiler generated by Buildroot is not able to generate 32 bits code. To solve this, we will rely on the host compiler being a x86 + x86-64 compiler. Therefore, this commit introduces the BR2_HOSTARCH_NEEDS_IA32_COMPILER option, which tells the dependency checking logic to verify that the host compiler is indeed capable of building x86 32 bits code.

Because the second approach is nicer, also build host-xz when xzcat is not available, using the host-prerequisite and suitable-host-pkg mechanisms, already used for tar.

2013-01-06Infrastructure to warn the user about missing 32 bits librariesThomas Petazzoni
Many users trying to use external toolchains on x86-64 machines get a very confusing message: "Can't execute cross-compiler" They get this message because they forgot to install the 32 bits compatibility libraries that are needed to run binaries compiled for x86 on x86-64 machines. Since this is the case for both external toolchains and certain binary-only tools like SAM-BA, we add a new Kconfig option BR2_HOSTARCH_NEEDS_IA32_LIBS, that packages must select if they need the 32 bits compatibility libraries. When this option is enabled, dependencies.sh checks that the 32 bits dynamic library loader is present on the system, and if not, it stops and shows an error. The path and name of the 32 bits dynamic loader is hardcoded because it is very unlikely to change, as it would break the ABI for all binaries. Also, it is worth noting that the check will be done even if we're running on a 32 bits machine. This is harmless, as 32 bits machines necessarily have the 32 bits dynamic loader installed, so the error will never show up in this case.

We should instead simply unset it at runtime, like we do for PKG_CONFIG_PATH. This reverts commit 9910eba33adb2b783b0df5d90a857816e82fbd55. Signed-off-by: Peter Korsgaard <jacmet@sunsite.dk>
2012-06-30dependencies: ensure that DESTDIR isn't set when running BuildrootThomas Petazzoni
Having DESTDIR set in the environment before running Buildroot creates some funky problems in the build process. Prevent users from running into this kind of troubles.

2012-02-09dependencies: build a host-tar if no suitable tar can be foundThomas De Schampheleire
Some toolchains, like the one built with buildroot itself, use hardlinks (for example to link between the c++ and g++ binary). Unpacking such a toolchain with the --strip-components options does not work correctly if the system tar is too old (<1.17). Even recent releases of RedHat/CentOS still ship with tar 1.15. This patch checks for a suitable tar version (tar 1.17+) on the host system, and adds host-tar to the host dependencies if none can be found. host-tar is download and extracted as cpio.gz instead of tar.gz, to prevent chicken-egg problem.

2012-02-09dependencies: add function suitable-host-packageThomas De Schampheleire
Sometimes, buildroot needs a certain host tool to do its job, e.g. tar. In many cases, we expect this tool to be present on the host system, but this is not always the case. Or maybe, the version on the host system is not suitable, and we need a more recent one. In some of these cases, instead of bailing out, buildroot could build the package first (but only if the existing system package is not suitable). To aid in detecting if a host package is suitable or not, this patch adds a function suitable-host-package. When called with parameter foo, it will execute check-host-foo.sh. This script should return either the path to the suitable host package, or the empty string if no suitable package can be found. The rules to determine whether something is suitable or not is left to check-host-foo.sh and depends on foo. An example usage of suitable-host-package is: DEPENDENCIES_HOST_PREREQ += $(if $(call suitable-host-package,foo),,host-foo) To avoid cluttering the existing dependencies.mk file, it includes any check-host-foo.mk file. These files can be used to hold appropriate dependency-related actions for foo.
