git-core-0.99.9g: mailinfo.c:448: undefined reference to `libiconv_open'

[Roberto Nibali]

Hello,

I've tried to compile git-core-0.99.9g on an old SuSE 9.1 box with a
self-compiled libiconv. Anyone can shed a light on the following?

gcc -o mailinfo.o -c -g -O2 -Wall -DSHA1_HEADER='<openssl/sha.h>' mailinfo.c
gcc -g -O2 -Wall -DSHA1_HEADER='<openssl/sha.h>' -o git-mailinfo
mailinfo.o libgit.a
mailinfo.o(.text+0x799): In function `convert_to_utf8':
/data/down/git-core-0.99.9g/mailinfo.c:448: undefined reference to
`libiconv_open'
mailinfo.o(.text+0x7f6):/data/down/git-core-0.99.9g/mailinfo.c:460:
undefined reference to `libiconv'
mailinfo.o(.text+0x801):/data/down/git-core-0.99.9g/mailinfo.c:461:
undefined reference to `libiconv_close'
collect2: ld returned 1 exit status
make: *** [git-mailinfo] Error 1

# nm /usr/local/lib/libiconv.so | grep -E "libiconv_open|libiconv_close"
0000f550 T libiconv_close
0000f580 T libiconv_open

I might be missing something really obvious. It's not very important;
just if you happen to know something regarding this issue I'd be interested.

Regards,
Roberto Nibali, ratz

As always, once you send the damn thing, the solution is obvious:

> gcc -o mailinfo.o -c -g -O2 -Wall -DSHA1_HEADER='<openssl/sha.h>' mailinfo.c
> gcc -g -O2 -Wall -DSHA1_HEADER='<openssl/sha.h>' -o git-mailinfo
> mailinfo.o libgit.a
> mailinfo.o(.text+0x799): In function `convert_to_utf8':

> 0000f580 T libiconv_open

# nm mailinfo.o | grep -i iconv
         U libiconv
         U libiconv_close
         U libiconv_open

The solution is simple:

make CFLAGS="-liconv"

Sorry for wasting your time,
