Error when compiling to ARM7

[j-bo]

When compiling to android arm7 on a linux host I get the following error :

blas_server.c: In function 'blas_thread_init':
blas_server.c:575:16: error: storage size of 'rlim' isn't known
  struct rlimit rlim;
                ^
blas_server.c:578:9: warning: implicit declaration of function 'getrlimit' [-Wimplicit-function-declaration]
         if(0 == getrlimit(RLIMIT_NPROC, &rlim)) {
         ^
blas_server.c:578:27: error: 'RLIMIT_NPROC' undeclared (first use in this function)
         if(0 == getrlimit(RLIMIT_NPROC, &rlim)) {
                           ^
blas_server.c:578:27: note: each undeclared identifier is reported only once for each function it appears in

  struct rlimit rlim;
                ^
make[1]: *** [blas_server.o] Erreur 1

Here's how I start the build :

make HOSTCC=gcc CC=arm-linux-androideabi-gcc NO_LAPACK=1 TARGET=ARMV7

I managed to correct the error modifying the file driver/others/blas_server.c from this :

#if defined(OS_LINUX) || defined(OS_NETBSD) || defined(OS_DARWIN)
#include <dlfcn.h>
#include <signal.h>
#include <sys/time.h>
#include <sys/resource.h>
#endif

To this :

#if defined(OS_LINUX) || defined(OS_NETBSD) || defined(OS_DARWIN)
#include <dlfcn.h>
#include <signal.h>
#include <sys/time.h>
#endif
#include <sys/resource.h>

It works but it obviously broke everything on other platforms ! Is there something as a OS_ARM define ?

There is OS_ANDROID (at least since a11555c) , though I wonder why this issue would not have come up in preparation or testing of that commit ? (But I have no experience with that platform)

Just got similar issue when compiling on FreeBSD. I had to pull out <signal.h> and <sys/resource.h>

@ryobg , sorry. I didn't test it on FreeBSD.

@xianyi, this is the only build error which I encountered. I suppose the FreeBSD macro can just be added next to the rest. Great work & thank you!
