[yocto] Issue with Python include directives

Thu Jul 10 01:42:05 PDT 2014

Hi,

I am trying to build gpsd-2.95 for ARM 32-bit using Yocto on a Ubuntu 12.04.4 64-Bit machine
I got the following compilation error

| arm-poky-linux-gnueabi-gcc -march=armv7-a -mthumb-interwork -mfloat-abi=hard -mfpu=neon -mtune=cortex-a15 -Wl,-O1 -Wl,--hash-style=gnu -Wl,--as-needed -L/home/user/project/build/tmp/sysroots/machine/usr/lib -lm --sysroot=/home/user/project/build/tmp/sysroots/machine -fno-strict-aliasing -DNDEBUG -g -fwrapv -O2 -Wall -Wstrict-prototypes -O2 -pipe -g -feliminate-unused-debug-types -Wall -Wcast-align -Wmissing-declarations -Wmissing-prototypes -Wstrict-prototypes -Wpointer-arith -Wreturn-type -D_GNU_SOURCE -fPIC -I/home/user/project/build/tmp/work/cortexa15hf-vfp-neon-poky-linux-gnueabi/gpsd/2.95-r10.0/gpsd-2.95 -I/usr/include/python2.7 -c gpspacket.c -o build/temp.linux-x86_64-2.7/gpspacket.o
| In file included from /usr/include/python2.7/Python.h:58:0,
|                  from gpspacket.c:8:
| /usr/include/python2.7/pyport.h:849:2: error: #error "LONG_BIT definition appears wrong for platform (bad gcc/glibc config?)."
| In file included from gpspacket.c:11:0:
| gpsd.h:327:0: warning: "SIZEOF_LONG" redefined [enabled by default]
| In file included from /usr/include/python2.7/Python.h:8:0,

| /usr/include/python2.7/pyconfig.h:992:0: note: this is the location of the previous definition
| gpspacket.c:244:1: warning: no previous prototype for 'initpacket' [-Wmissing-prototypes]
| error: command 'arm-poky-linux-gnueabi-gcc' failed with exit status 1

In the tmp/.../gpsd-2.95 folder, I just executed directly the arm-poky-linux-gnueabi-gcc command with the same arguments except I replaced -I/usr/include/python2.7 with -I/home/user/project/build/tmp/sysroots/machine/usr/include/python2.7
Now the compilation command was successful.

But now the problem is, how do I change the -I/usr/include/python2.7 with -I/home/user/project/build/tmp/sysroots/machine/usr/include/python2.7 which is passed as an argument for the arm-poky-linux-gnueabi-gcc using the recipe files ?

Thanks,
B.Sathish Kumar
