I hope this is the right section of the forum to post this. I don't know if this is a bug or just user error. 
Like the topic title says, I'm trying to compile Mednafen 0.9.22-WIP with all emulation cores enabled (including PSX) but I keep getting the same error during "make." My system is an Intel Mac Mini with a Core 2 Duo processor and Mac OS X 10.5.8. I've got Xcode and all needed libraries installed except for jack. I'm quite sure that something in the PSX core is halting the compile because the make log says so. Also, when I use "--disable-psx" with configure, mednafen compiles without error and runs fine afterwards.
The following are the two commands I run:
| Quote: |
./configure --enable-static --disable-shared --disable-jack
|
Configure completes without errors, but make errors out with the following:

I'm hoping the problem is something simple, like I need to add a switch to configure or change an environment variable. Below are the logs for configure and make. Thank you for any help you can provide.
EDIT: Changed the title to add "[SOLVED]"

The version of gcc you seem to be using(4.0.1) is realllly old.
You can try replacing masmem.h with the attached file.

That worked great! It compiles just fine now. Thank you. For anyone that's curious the modified "masmem.h" file from above changes line 108 from:
| Quote: |
max_unit_type pre_padding[pre_padding_count];
|
to:
| Quote: |
max_unit_type pre_padding[pre_padding_count ? pre_padding_count : 1];
|
and line 117 from:
| Quote: |
max_unit_type post_padding[post_padding_count];
|
to:
| Quote: |
max_unit_type post_padding[post_padding_count ? post_padding_count : 1];

Unfortunately for people stuck with Mac OS X 10.5.8, gcc 4.0.1 is the last version of the compiler provided by Xcode. This modification should help others trying to build this excellent emulator on their outdated Macs. Thanks for offering a fix when the problem was on my end.
On a side note, it's great to see PSX emulation working so well on my Mac. If this really is the alpha stage of PSX emulation for Mednafen, then I can't wait to see the final version.
