Hello all, Any help on this would be very much appreciated as I am completely stuck.
I am having trouble repackaging a shared library using the Automake, libtool, and Autoconf. I have been able to successfully build a distribution that installs the shared library correctly, but when I try to compile a test program that uses the library, the following error occurs: [jks@saba newsmdi]$ gcc -g -lsmdi -o test firsttest.c /usr/local/lib/libsmdi.so: undefined reference to `pthread_create' collect2: ld returned 1 exit status The shared library uses functions from the pthreads library, so I tried adding LDADD= pthread, libsmdi_la_LTLDADD = pthread, and some other variations to my Makefile.am, and none of them worked. It seems that the shared library is being built but not properly linked to the other libraries that it depends on. Will someone please let me know what I need to do to portably link to an existing library (Makefile.am and configure.in listed below). Thanks in advance for the help; I have looked through the docs and searched the net with no luck. Thanks, John ----- Makefile.am: ## Process this file with automake to produce Makefile.in lib_LTLIBRARIES = libsmdi.la libsmdi_la_SOURCES = smdi.c aspi.linux.c libsmdi_la_LDFLAGS = -version-info 0:5:0 libsmdi_la_LTLDADD = pthread include_HEADERS = aspi.h smdi.h ----- configure.in dnl Process this file with autoconf to produce a configure script. dnl From Autoconf manual: dnl Autoconf requirements dnl AC_INIT(package, version, bug-report-address) dnl information on the package dnl checks for programs dnl checks for libraries dnl checks for header files dnl checks for types dnl checks for structures dnl checks for compiler characteristics dnl checks for library functions dnl checks for system services dnl AC_CONFIG_FILES([file...]) dnl AC_OUTPUT AC_INIT(aspi.linux.c) AM_INIT_AUTOMAKE(opensmdi, 0.0.5) AM_PROG_LIBTOOL dnl Checks for programs. dnl Checks for libraries. dnl Checks for header files.
