It's a long time since I had a problem compiling R, but I've now encountered one with R-2.6.2 on Fedora Core 6 (64bit).
The problem arises when the installation process gets to the grid package, the unit.c part in particular. This is the output I get: gcc -std=gnu99 -I../../../../include -I../../../../include -I/usr/local/include -fvisibility=hidden -fpic -g -O2 -c unit.c -o unit.o unit.c: In function ��pureNullUnit��: unit.c:332: error: stray ��#�� in program unit.c:332: error: �?R_fcall�� undeclared (first use in this function) unit.c:332: error: (Each undeclared identifier is reported only once unit.c:332: error: for each function it appears in.) make[5]: *** [unit.o] Error 1 make[5]: Leaving directory `/usr/local/R-2.6.2/src/library/grid/src' make[4]: *** [all] Error 2 make[4]: Leaving directory `/usr/local/R-2.6.2/src/library/grid/src' make[3]: *** [all] Error 1 make[3]: Leaving directory `/usr/local/R-2.6.2/src/library/grid' make[2]: *** [R] Error 1 make[2]: Leaving directory `/usr/local/R-2.6.2/src/library' make[1]: *** [R] Error 1 make[1]: Leaving directory `/usr/local/R-2.6.2/src' make: *** [R] Error 1 I installed the same tgz file on a 32-bit Mepis machine and on a CentOS5 machine without such any problem . All previous 64bit compilations have also been without a problem. There has been a problem with one PCI slot on the machine in question after an electrical misadventure. If nobody else has had a problem on 64 bit machines, could it be that I have a hardware problem? Seems a bit unlikely it would get as far as it did were that the case, but I could be convinced otherwise. Ideas? Other experience? -- ~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~. ___ Patrick Connolly {~._.~} Great minds discuss ideas _( Y )_ Middle minds discuss events (:_~*~_:) Small minds discuss people (_)-(_) .....
