From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.12) Gecko/20050922 Fedora/1.0.7-1.1.fc4 Firefox/1.0.7 Description of problem: When using isspace etc from ctype.h the binary fails to link statically. I have not tried to change from compat_symbol to versioned_symbol and recompile like suggested at http://nixdoc.net/files/forum/about49448.html, but I feel it would be an error if I had to recompile glibc in order to link statically. Version-Release number of selected component (if applicable): glibc-2.3.5-10.3 How reproducible: Always Steps to Reproduce: prompt>cat main.c #include <ctype.h> int main(int argc, char *argv[]) { return isspace('A'); } prompt>gcc -Wall main.c -o main prompt>gcc -Wall -static main.c -o main /tmp/ccCeNztK.o(.text+0x1d): In function `main': main.c: undefined reference to `__ctype_b@GLIBC_2.0' collect2: ld returned 1 exit status prompt>gcc -Wall main.c -E | grep isspace extern int isspace (int) __attribute__ ((__nothrow__)); prompt>gcc -Wall -static main.c -E | grep isspace extern int isspace (int) __attribute__ ((__nothrow__)); prompt>rpm -q gcc gcc-4.0.1-4.fc4 prompt>rpm -qf /usr/include/ctype.h glibc-headers-2.3.5-10.3 prompt>rpm -qf /lib/libc.so.6 glibc-2.3.5-10.3 prompt>objdump -T /lib/libc.so.6 | grep __ctype_b 00a1aa58 g DF .text 0000003e GLIBC_2.3 __ctype_b_loc 00b1e428 g DO .data 00000004 (GLIBC_2.0) __ctype_b prompt> Actual Results: link error Expected Results: no link error Additional info:
Can't reproduce. Are you sure you aren't preprocessing or compiling on some old system (more than a couple of years old) and then linking on FC4? gcc -Wall -static a.c -E | grep -A3 main; gcc -static -o a a.c; ./a; echo $?; rpm -q glibc glibc-devel int main(int argc, char *argv[]) { return ((*__ctype_b_loc ())[(int) (('A'))] & (unsigned short int) _ISspace); } 0 glibc-2.3.5-10.3 glibc-devel-2.3.5-10.3 readelf -Ws /usr/lib/libc.a | grep __ctype_b 6: 00000000 50 FUNC GLOBAL DEFAULT 1 __ctype_b_loc
No feedback provided, closing as WORKSFORME, as I can't reproduce it.
