From 8cee09b59a8c1ff2ebfc8c46097825d2eafdc4dd Mon Sep 17 00:00:00 2001 From: Thomas Petazzoni Date: Sat, 16 May 2015 17:32:13 +0200 Subject: [PATCH] Fix static linking problem with libgcrypt When libgcrypt is used, it is linked with libgpg-error, so we should also test that libgpg-error is available, and include -lgpg-error in the LIBS variable. This fixes build issues like: CCLD xml /home/thomas/projets/buildroot/output/host/usr/bfin-buildroot-uclinux-uclibc/sysroot/usr/lib/libexslt.a(crypto.o): In function `_exsltCryptoGcryptInit': crypto.c:(.text+0x112): undefined reference to `_gcry_check_version' /home/thomas/projets/buildroot/output/host/usr/bfin-buildroot-uclinux-uclibc/sysroot/usr/lib/libexslt.a(crypto.o): In function `_exsltCryptoRc4DecryptFunction': crypto.c:(.text+0x316): undefined reference to `_gcry_cipher_open' crypto.c:(.text+0x32a): undefined reference to `_gcry_strerror' crypto.c:(.text+0x34c): undefined reference to `_gcry_cipher_setkey' Which are caused by the AC_SEARCH_LIBS() test for libgcrypt to fail due to -lgpg-error not been present in the LIBS variable. Note that using PKG_CHECK_MODULES() would be a much much better replacement than this complicated handling of static libraries, but it's a much more significant effort.
