Hi, I have a problem when i use the command "sudo port install mlt" the file "transition_composite.c" doesn't compile and the error is :

/usr/bin/llvm-gcc-4.2 -O2 -I/opt/local/include -I/opt/local/include -DARCH_X86_64 -Wall -DPIC   -O2 -pipe -fno-tree-dominator-opts -fno-tree-pre -DUSE_MMX -DUSE_SSE -DUSE_SSE2 -g -D_FILE_OFFSET_BITS=64 -D_LARGEFILE_SOURCE -fPIC -D__DARWIN__ -I/opt/local/include/SDL -D_GNU_SOURCE=1 -D_THREAD_SAFE -DARCH_X86_64 -Wall -DPIC   -O2 -pipe -fno-tree-dominator-opts -fno-tree-pre -DUSE_MMX -DUSE_SSE -DUSE_SSE2 -g -D_FILE_OFFSET_BITS=64 -D_LARGEFILE_SOURCE -fPIC -D__DARWIN__ -I/opt/local/include/SDL -D_GNU_SOURCE=1 -D_THREAD_SAFE -I../.. -DARCH_X86_64 -Wall -DPIC   -O2 -pipe -fno-tree-dominator-opts -fno-tree-pre -DUSE_MMX -DUSE_SSE -DUSE_SSE2 -g -D_FILE_OFFSET_BITS=64 -D_LARGEFILE_SOURCE -fPIC -D__DARWIN__ -I/opt/local/include/SDL -D_GNU_SOURCE=1 -D_THREAD_SAFE   -c -o transition_composite.o transition_composite.c

Please help me.

It might help Dan diagnose the problem if you attached the main.log file.

It might be a compiler-specific problem, in which case you might be able to work around it by using a different compiler.

Using clang instead of llvm

I'm also affected, and reproduced the problem with two different compilers. Clang gave a more informative error message:

D'oh, fuck WikiFormatting. It's readable in main.2.log.

On my system, if I change -O2 to -O1 then the problem goes away, but I do like that change and want to figure out real reason.

[mikyboum@…]

thank you for your comments. Can you help me because i can't use "port install mlt" ? it doesn't work ? i don't know where to change the file

[mikyboum@…]

i attach my main.log. Please help me, my system is Macbook Pro Mac OS X v10.6.8.

[ddennedy (Dan Dennedy)]

I have attached the fixes. If you are observing this bug but do not have experience with local ports, then you can wait for the patches to be accepted or try to learn how to use local ports from the Guide.

[jimrandomh@…]

I confirm that the patch fixes the problem for me.

[mikyboum@…]

thank you very much it works.

[ddennedy (Dan Dennedy)]

I just added a newer patch to because previous one created regression building on 32-bit.

[jmroot (Joshua Root)]

Do you want to commit this patch? Or just update to 0.8.2?

[ddennedy (Dan Dennedy)]

Yesterday, I was using MacPorts and realized I had not updated my port to 0.8.2. I will do that now.

see ticket #36154 for the port upgrade
