• Product: Gentoo Linux
• Status: RESOLVED TEST-REQUEST

[Description Kyle A Bishop 2006-04-30 18:42:41 UTC]

Hello,

When attempting to emerge the lastest version of flightgear (0.9.10) I receive the following compile error:

i686-pc-linux-gnu-gcc  -O3 -march=athlon-xp -fomit-frame-pointer -pipe -D_REENTRANT  -L/usr/games/lib -L/usr/X11R6/lib -L/usr/local/lib -o gl-info  gl-info.o -lglut -lGLU -lGL -lXmu -lXt -lSM -lICE -lXi -lXext -lX11 -ldl -lm

then mv -f ".deps/al-info.Tpo" ".deps/al-info.Po"; else rm -f ".deps/al-info.Tpo"; exit 1; fi
al-info.c: In function `main':
al-info.c:29: error: `ALCint' undeclared (first use in this function)
al-info.c:29: error: (Each undeclared identifier is reported only once
al-info.c:29: error: for each function it appears in.)
al-info.c:29: error: syntax error before "i"

make[1]: Leaving directory `/var/tmp/portage/flightgear-0.9.10/work/FlightGear-0.9.10/tests'
make: *** [all-recursive] Error 1

I poked around a little bit and found that in the file tests/al-info.c the code was attempting to declare several variables of type "ALCint". On closer examination I found that in the librarys that it includes, there was no such data type. However, by changing these types from ALCint to ALint, I was able to get the package to compile succefully and everything works.

I will include a patch file after this that includes the change I made in order to make it compile cleanly.

Below is the obligatory emerge --info and relevant package information:

Created attachment 85892 [details, diff]
Apply to fix al-info.c to use the correct data types.

Apply this patch in the unpacked flightgear directory to fix tests/al-info.c

Would you mind resyncing portage, updating your system and retest  flightgear without any patch. ALCint is defined in openal, current version, so you should get it.
