[pdf-devel] libgcrypt when cross-compiling with mingw32

[Aleksander Morgado]

Hi,

The AM_PATH_LIBGCRYPT macro from m4/libgcrypt.m4 will check the 
existence of the libgcrypt library and its version. But it doesn't work 
when cross-compiling with mingw32, as it doesn't look for libgcrypt in 
the mingw32 environment.

When running configure with the mingw32 host:
$> ./configure --host=i586-mingw32msvc --without-zlib --enable-nocheck
...
checking for libgcrypt-config... /usr/bin/libgcrypt-config
checking for LIBGCRYPT - version >= 1.2.4... yes (1.4.1)
...

I was expecting a crash here, as I don't have libgcrypt in mingw32 
environment. (If I try to compile, it won't, of course).


Why don't we use AC_CHECK_LIB() to check for libgcrypt? If we want the 
>=1.2.4 check we can put in AC_CHECK_LIB a function which is available 
in 1.2.4 and not in previous versions.

Cheers,
