Package: check

Hello,
libcheck_pic.a currently can't be linked in:
$ cat test.c
extern void pack();
int main(void) {
return pack;
}
$ gcc test.c -o test $(pkg-config --libs check)
test.c: In function 'main':
test.c:3:2: warning: return makes integer from pointer without a cast [enabled
by default]
return pack;
^
/usr/bin/ld:
/usr/lib/gcc/x86_64-linux-gnu/4.8/../../../x86_64-linux-gnu/libcheck_pic.a(check_pack.o):
undefined reference to symbol '__pthread_unregister_cancel@@GLIBC_2.3.3'
/lib/x86_64-linux-gnu/libpthread.so.0: error adding symbols: DSO missing from
command line
collect2: error: ld returned 1 exit status
-lpthread is indeed missing from the PTHREAD_LIBS: buildd logs show:
checking for the pthreads library -lpthreads... no
checking whether pthreads work without any flags... yes
This seems to get through because -fPIC is passed in CFLAGS: building in
a wheezy pbuilder gives me the following details:
configure:15481: gcc -o conftest -g -O2 -fPIC -Wall -ansi -pedantic -Wextra
-Wstrict-prototypes -Wmissing-prototypes -Wwrite-strings -Wno-variadic-macros
conftest.c -lrt -lm >&5
conftest.c:86:1: warning: function declaration isn't a prototype
[-Wstrict-prototypes]
conftest.c: In function 'main':
conftest.c:89:22: warning: null argument where non-null required (argument 1)
[-Wnonnull]
conftest.c:90:22: warning: null argument where non-null required (argument 1)
[-Wnonnull]
conftest.c:90:22: warning: null argument where non-null required (argument 3)
[-Wnonnull]
conftest.c:88:27: warning: 'th' is used uninitialized in this function
[-Wuninitialized]
configure:15481: $? = 0
configure:15490: result: yes
and thus the pthread_create unresolved symbol gets through! When I
rebuild the package myself in a sid pbuilder, I however properly get
checking for the pthreads library -lpthreads... no
checking whether pthreads work without any flags... no
checking whether pthreads work with -Kthread... no
checking whether pthreads work with -kthread... no
checking for the pthreads library -llthread... no
checking whether pthreads work with -pthread... yes
and indeed, gcc now seems to refuse the unresolved symbol.
configure:15481: gcc -o conftest -g -O2 -fPIC -Wall -ansi -pedantic -Wextra
-Wstrict-prototypes -Wmissing-prototypes -Wwrite-strings -Wno-variadic-macros

So it looks like rebuilding with the newer toolchain
would fix the issue, but you would probably want to pass
-Wl,--no-allow-shlib-undefined along -fPIC, to avoid the issue with any
version of gcc.
