Here are some other interesting points on pcsc and gcc on Solaris 10.
I have been able to compile with gcc on Sparc, but on an i386 system,
I get the same type of failures Kevin has reported.
The issue appears to be in misc.h in the use of the gcc __attribute__
#define INTERNAL __attribute__ ((visibility("hidden")))
If I use the attached patch, to misc.h to not use this.
pcsc now compiles on both sparc and i386 using Suns /usr/sfw/bin/gcc.
This would also explain why the Sun Studio cc works, as it does not
use the INTERNAL either.
Without the patch:
On sparc Solaris 10, this the attribute is ignored with many warnings like:
../../src/src/sys_unix.c:403: warning: visibility attribute not supported in
this configuration; ignored
../../src/src/sys_unix.c: In function `SYS_GetSeed':
But on i386, they are not ignored, but then the link has problems like this:
