Hi,

I am trying to add a new package to buildroot. the package is built upon
autotools. thus, it is supposed to be very easy to make it
cross-compilable. ever, i got suck at AC_CHECK_LIB macro. it doesn't
work well at cross-compiling while it does work on normal compiling.

AC_CHECK_LIB([fcgi], [FCGX_InitRequest], [AC_MSG_WARN("unable to find
the FCGX_InitRequest() function")])

always failed even though I do have libfcgi in my configuration. The
error message looks like

checking for FCGX_InitRequest in -lfcgi... no
configure: WARNING: unable to find the FCGX_InitRequest() function

I don't think AC_CHECK_LIB will not work on cross-compiling because it
seems there are lots of other target packages in buildroot using the
macro. Most probably, I am doing something wrong.

Does AC_CHECK_LIB work in buildroot? If the macro needs some changes,
how could I do it?

Thanks,
/Adam

What do you have in config.log for the FCGX_InitRequest check?

Thank you, Baruch.

Here is what I got from grep in config.log.

$ grep -i FCGX_InitRequest output/build/visage-master/config.log
configure:5626: checking for FCGX_InitRequest in -lfcgi
| char FCGX_InitRequest ();
| return FCGX_InitRequest ();
configure:5689: WARNING: unable to find the FCGX_InitRequest() function
ac_cv_lib_fcgi_FCGX_InitRequest=no

I have also attached 'config.log' as well.

This file contains any messages produced by compilers while
running configure, to aid debugging if configure makes a mistake.

It was created by visage configure 0.1, which was
generated by GNU Autoconf 2.69.  Invocation command line was

The interesting part in your config.log is

	libfcgi.so: undefined reference to `frexp'

This means that libfcgi.so depends on the math library (libm), but you didn't 
add it to the compile command line (-lm). Please try adding -lm to the 
AC_CHECK_LIB macro OTHER-LIBRARIES parameter as follows:

	AC_CHECK_LIB([fcgi], [FCGX_InitRequest], [LIBS="$LIBS -lfcgi],
		[AC_MSG_WARN("unable to find the FCGX_InitRequest() function")],
		[-lm])

Em...I can understand the issue now. However, would it be possible for 
libfcgi to resolve its dependency somehow?

Dear Adam Jiang,

On Thu, 25 Dec 2014 22:03:02 +0900, Adam Jiang wrote:

For dynamic linking, this should happen automatically, provided libfcgi
is properly linked against libm. But indeed, after a quick look, it
turns out that libfcgi uses frexp() but isn't linked against libm:

$ readelf -a libfcgi.so.0.0.0
[...]
  Tag        Type                         Name/Value
 0x00000001 (NEEDED)                     Shared library: [libnsl.so.0]
 0x00000001 (NEEDED)                     Shared library: [libpthread.so.0]
 0x00000001 (NEEDED)                     Shared library: [libc.so.0]
 0x0000000e (SONAME)                     Library soname: [libfcgi.so.0]
[...]
   176: 00000000     0 NOTYPE  GLOBAL DEFAULT  UND frexp

To me, this looks like a bug in libfcgi build system.

However, even if libfcgi is linked against libm, this will not solve
the case of static linking. In this case, the only proper solution
would be to extend libfcgi to install a .pc (pkg-config) file, and have
your package use PKG_CHECK_MODULES() instead of AC_CHECK_LIB().

Best regards,

Thomas

Probably, the dependency on '-lm' issue is caused by difference between 
glibc and uclibc. Does uclibc split math library into another library 
and don't implicitly include it?
