I've made a simple example. Here is the file:
#include <iostream>
#include <cilk/cilk.h>
#include <iostream>
#include <cilk/cilk.h>
#define UNROLL_SCATTER 2
#define INLINE_SCATTER 1
#define CILK_FOR_GRAINSIZE 128
#if INLINE_SCATTER==0
void CoinAbcScatterUpdate(int number);
#else
void CoinAbcScatterUpdate(int number)
{
int result = 0;
#if UNROLL_SCATTER==0
std::cout << "test1" << std::endl;
#elif UNROLL_SCATTER==1
std::cout << "test2" << std::endl;
#elif UNROLL_SCATTER==2
std::cout << "test3" << std::endl;
#pragma cilk grainsize=CILK_FOR_GRAINSIZE
cilk_for(int j=0; j < number; j+=2) {
result+=j;
}
#elif UNROLL_SCATTER==3
std::cout << "test4" << std::endl;
#endif
}
#endif
int main() {
return 0;
}
When I compile this example as an executable, everything is fine.
$ g++ -fcilkplus test.cpp -o test.o
If I compile the file as an object file, I meet the same error message:
$ g++ -c -fcilkplus test.cpp -o test.o
test.cpp: Dans la fonction ‘void CoinAbcScatterUpdate(int)’:
test.cpp:24:24: erreur: ‘CILK_FOR_GRAINSIZE’ was not declared in this scope
#pragma cilk grainsize=CILK_FOR_GRAINSIZE
^
test.cpp:24:9: erreur: invalid grainsize for _Cilk_for
#pragma cilk grainsize=CILK_FOR_GRAINSIZE
^
A gcc bug ?

Objet: [Cbc] Cbc-2.9.7 doesn't compile with gcc-5
Hello,
I downloaded Cbc-2.9.7 to compile it on fedora 23 64 bits.
I wanted to compiled Cbc with aboca enabled.
Here is my command line:
./configure --prefix=/opt/cbc-2.9.7 --enable-aboca=4
And some of the errors I've got:
if /bin/sh ../../libtool --tag=CXX --mode=compile g++ -DHAVE_CONFIG_H -I. -I`echo .` -I/home/admin/tmp/Cbc-2.9.7/CoinUtils/src -DCOIN_HAS_CLP -O3 -pipe -DNDEBUG -pedantic-errors -Wparentheses -Wreturn-type -Wcast-qual -Wall -Wpointer-arith -Wwrite-strings -Wconversion -Wno-unknown-pragmas -Wno-long-long -DCLP_BUILD -MT ClpCholeskyDense.lo -MD -MP -MF ".deps/ClpCholeskyDense.Tpo" -c -o ClpCholeskyDense.lo ClpCholeskyDense.cpp; \
then mv -f ".deps/ClpCholeskyDense.Tpo" ".deps/ClpCholeskyDense.Plo"; else rm -f ".deps/ClpCholeskyDense.Tpo"; exit 1; fi

Next, I configured cbc with the following command line:
./configure --prefix=/opt/cbc-2.9.7 --enable-aboca=4 CXXFLAGS=-fcilkplus
And now, I meet the following error message:
