Flag --enable-fribidi does not add "-lfribidi" to compiler flags

[patrick.atoon@…]

I tried configuring and compiling with the "--enable-fribidi" flag, which resulted in a build error due to undefined fribidi symbols:

Undefined symbols for architecture i386:

"_fribidi_charset_to_unicode", referenced from:

_do_fribid_log2vis in subreader.o
_sub_fribidi in subreader.o

"_fribidi_log2vis", referenced from:

_sub_fribidi in subreader.o

ld: symbol(s) not found for architecture i386
collect2: ld returned 1 exit status
make: * [mencoder] Error 1

The huge line above (won't paste it here) explains why: the flag "-lfribidi" is missing in the compile command.

The cause appears to be the "configure" script (line 6066) where the variable "ld_tmp" is still empty from its initialization on line 6041.

I changed the following lines:

if test "$_fribidi" = yes ; then

def_fribidi='#define CONFIG_FRIBIDI 1'
extra_cflags="$extra_cflags $inc_tmp"
extra_ldflags="$extra_ldflags $ld_tmp"

else

to these and compilation works:

if test "$_fribidi" = yes ; then

def_fribidi='#define CONFIG_FRIBIDI 1'
ld_tmp='-lfribidi'
extra_cflags="$extra_cflags $inc_tmp"
extra_ldflags="$extra_ldflags $ld_tmp"

else

This sounds like expected behaviour (if you specify --enable-fribidi, you also have to set --extra-cflags and --extra-ldflags).

What happens if you do not specify --enable-fribidi? It should be auto-detected.

[patrick.atoon@…]

Fribidi is not autodetected without --enable-fribidi.

Here is the relevant output:

---

Checking for fribidi with charsets ... Package fribidi was not found in the pkg-config search path.
Perhaps you should add the directory containing `fribidi.pc'
to the PKG_CONFIG_PATH environment variable
No package 'fribidi' found

I tried supplying the --extra-cflags and --extra-ldflags, but that results in a configure error:

---

./configure --cc=$GCC2 --disable-x11 --disable-gl --disable-qtx --disable-theora --disable-libvorbis --with-freetype-config=$TARGET/bin/freetype-config --prefix=$TARGET --enable-fribidi --extra-cflags=-lfribidi --extra-ldflags=-lfribidi

Error: Compiler is not functioning correctly. Check your installation and custom CFLAGS -O4 -fomit-frame-pointer -pipe -mmacosx-version-min=10.6 -isystem /Developer/SDKs/MacOSX10.6.sdk -arch i386 -I/tmp/i386/target/include .

---

To work around that error I can of course add "-lfribidi" to the CFLAGS and LDFLAGS.

It merely occurred to me as strange that the configure code seems to set ld_tmp and inc_tmp in the bit above, but it skips such initialization when --enable-fribidi is defined.

If this is normal behavior and not a bug, I'll just use the workaround and close this issue.

[cehoyos]

Please post the part of config.log (after running without --enable-fribidi) beginning with "Checking for fribidi" and ending with "Result is..."

(The expected behaviour is of course that auto-detection works.)

[patrick.atoon@…]

Sure, here you go:

#include <stdlib.h>
/* workaround for fribidi 0.10.4 and below */
#define FRIBIDI_CHARSET_UTF8 FRIBIDI_CHAR_SET_UTF8

if (fribidi_parse_charset("UTF-8") != FRIBIDI_CHAR_SET_UTF8)

exit(1);

return 0;

Result is: yes

Your last post indicates that fribidi does get auto-detected if --enable-fribidi is not passed to configure ("Result is: yes", this is the intended behaviour), but in the post before you wrote that "Fribidi is not auto-detected".

Could you elaborate?

[diego@…]

The described behavior is not a bug and autodetection is working fine.
