would you like the warning messages from a build?

[david]

I have notice a lot of warnings when compiling on mandriva linux, I was wondering if you would like the warning output of the build. Of course next time I build, or are warnings a necessary evil? David

[Philip Taylor]

Are they basically the same warnings as in ​this log? There's a few groups:

• Warnings in third-party libraries (before the "/usr/bin/make CONFIG=Release -j4" line, and ones in wxJS directories) aren't ours to fix.
• unused parameter warnings are intentional (they're pointing out code that hasn't been written yet).
• ignoring return value warnings are boring (they're for error handling in code that isn't even used) but probably should be fixed.
• archive_zip.cpp warnings are bogus (the code is correct but the compiler can't prove it); r8429 should stop them.
• The part saying

  /usr/include/bits/string3.h: In function 'void TestMD5::T.881()':
  /usr/include/bits/string3.h:52: warning: array subscript is above array bounds
  /usr/include/bits/string3.h:52: warning: array subscript is above array bounds
  

  looks like it might just be a compiler bug - I can reproduce it with GCC 4.4.4 (it warns first from TestMD5::test_chunks first calling m.Update) but not 4.3.4 or 4.5.0, and the code looks correct as far as I can tell.

Do you get any different warnings to these?

[david]

I didn't mean "Of course next time I build, or are warnings a necessary evil?" in any derogatory way. It's not easy making cross compiling applications.
Basically everything is being built it's just pyrogenesis_dbg segment faults after the first two speed tests. A list of the required header files would make it easier for me to find the packages I need to compile it, because packages change on a daily basis and mandriva does not utilize version packaging on every package, I don't know why they don't just for the sake of LAMP.

The thing is I cannot have both packages libJpeg62 and libjpeg version 8 installed at the same time, but I don't think that should matter. Anywho YOu can probably make more sense of this than I can.

(Sorry, forgot to reply earlier.)

Replying to dsims:

Basically everything is being built it's just pyrogenesis_dbg segment faults after the first two speed tests.

Hmm, segmentation faults don't sound good! Can you run it in gdb to find where it's failing? (Run "gdb ./pyrogenesis_dbg" then enter "r" to run, and hopefully it'll crash, then enter "bt full" to see the location.)

A list of the required header files would make it easier for me to find the packages I need to compile it, because packages change on a daily basis and mandriva does not utilize version packaging on every package

The BuildInstructions page has a list of the tools and libraries that are required. In general, any versions that aren't more than a few years old ought to work.

The thing is I cannot have both packages libJpeg62 and libjpeg version 8 installed at the same time, but I don't think that should matter.

Given the warning:

/usr/bin/ld: warning: libjpeg.so.8, needed by /usr/lib/libtiff.so.3, may conflict with libjpeg.so.62

it sounds like libtiff and the game are being compiled with inconsistent versions of libjpeg. I think you shouldn't need to have multiple versions installed - everything should use the same one. Maybe something is a bit broken in the Mandriva packages you're using, but I'm afraid I don't know any details that would help :-(

[Philip Taylor]

Closing due to lack of activity; feel free to reopen if there's still a problem. (Warnings all seem to be either fixed or unfixable, and the segmentation fault looks like a system configuration error.)
