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:

/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.
