Bug 58563 – libmpeg2-0.4.0b fails to compile (uses O_BINARY)

• Status: RESOLVED WORKSFORME
• Product: Gentoo Linux

[Description Felix von Leitner 2004-07-27 09:58:50 UTC]

emerging libmpeg2-0.4.0b fails:

mpeg2dec.c: In function `main':
mpeg2dec.c:766: warning: implicit declaration of function `setmode'
mpeg2dec.c:766: error: `O_BINARY' undeclared (first use in this function)
mpeg2dec.c:766: error: (Each undeclared identifier is reported only once
mpeg2dec.c:766: error: for each function it appears in.)


When I add #define O_BINARY 0 to unistd.h, it still fails at link time, because the linker can not resolve "setmode".

Reproducible: Always
Steps to Reproduce:
1. emerge media-libs/libmpeg2-0.4.0-b

That's it.  I'm using ~x86 with glibc 2.3.4.20040619 and gcc 3.4.1.
Actual Results:  
build fails.

Expected Results:  
compile through and install package.

Portage 2.0.50-r9 (default-x86-1.4, gcc-3.4.1, glibc-2.3.4.20040619-r0, 2.6.7)

I'll check this out.

[Comment 2 Chris White (RETIRED) 2004-07-27 12:08:27 UTC]

Can you post your linux-headers version please?

[Comment 3 Travis Tilley (RETIRED) 2004-07-27 12:12:25 UTC]

it compiles fine here on amd64 with gcc 3.4.1, so it's not a general gcc 3.4 error if that helps any.

works fine here using gcc-3.4.1 and glibc-2.3.4.20040619-r1.
for me it's linux26-headers-2.6.7-r4

I'd try and re-create this again.

One thing I will mention:

`-mcpu=' is deprecated. Use `-mtune=' or '-march=' instead.

I'd try as it says and see if you get the error again.  Also, you might want
to upgrade to gcc 3.4.2 which has some bug fixes here and there.
