[R] How to build R-base on Mandrake 8.1 ?

[mikalzet@libero.it]

I have recently done a clean install of Mandrake 8.1 and am trying to
compile R with an aim to preparing a working RPM.
If anyone has managed to compile R-base on a Mandrake 8.1 please tell me.
When I try, R-base build keeps on failing both with gcc-2.96 and
gcc-3.0.1, no matter what the optimizations. The details vary according to
the choice of compiler and options, but failure is during build of lapack.
Installing the liblapack3 and liblapack3-devel rpms present on the
Mandrake 8.1 distribution hasn't solved the problem.

Switching between versions of gcc is simple, as /usr/bin/gcc is actually a
link to /etc/alternatives/gcc which is a link to /usr/bin/gcc-2.96 but can
be changed to /usr/bin/gcc-3.0.1 (or even /usr/bin/kgcc which immediately
gives "/usr/include/stdio.h:300 parse error before `__gnuc_va_list' ").

The following examples were run cleanly, i.e. the entire old build directory
was cancelled each time. Result: five different errors in double.f, one in
cmplx.f. I have kept the config.cache and config.log if anyone is
interested.


Example 1:
		gcc 3.0.1, no optimizations set in R-base.spec
....
gcc -I. -I../../../src/include -I../../../src/include -I/usr/local/include
-DHAVE_CONFIG_H -mieee-fp -D__NO_MATH_INLINES -fPIC  -g -O2 -c Lapack.c -o
Lapack.lo
g77  -fPIC  -g -O2 -c double.f -o double.lo
double.f: In subroutine `dgees':
double.f:2362: Internal error: Segmentation fault.


Example 2:
		gcc 3.0.1, CFLAGS and FFLAGS set to $RPM-OPT-FLAGS but
		-ffast-math removed (this flag has always caused R build
		to fail in the past)
....
gcc -I. -I../../../src/include -I../../../src/include -I/usr/local/include
-DHAVE_CONFIG_H -mieee-fp -D__NO_MATH_INLINES -fPIC  -O3
-fomit-frame-pointer -pipe -mcpu=pentiumpro -march=i586
-fno-strength-reduce -c Lapack.c -o Lapack.lo
g77  -fPIC  -O3 -fomit-frame-pointer -pipe -mcpu=pentiumpro -march=i586
-fno-strength-reduce -c double.f -o double.lo
double.f: In subroutine `dbdsqr':
double.f:731: Internal error: Segmentation fault.


Example 3:
		gcc 3.0.1, $RPM-OPT-FLAGS enabled
....
gcc -I. -I../../../src/include -I../../../src/include -I/usr/local/include
-DHAVE_CONFIG_H -mieee-fp -D__NO_MATH_INLINES -fPIC  -O3
-fomit-frame-pointer -pipe -mcpu=pentiumpro -march=i586 -ffast-math
-fno-strength-reduce -c Lapack.c -o Lapack.lo
etc.    gives a segmentation fault in yet another subroutine of double.f


Example 4:
                gcc 2.96, no optimizations set in R-base.spec
....
make[4]: Entering directory
`/home/mike/rpm/BUILD/R-1.3.1/src/modules/lapack'
gcc -I. -I../../../src/include -I../../../src/include -I/usr/local/include
-DHAVE_CONFIG_H -mieee-fp -D__NO_MATH_INLINES -fPIC  -g -O2 -c Lapack.c -o
Lapack.lo
g77  -fPIC  -g -O2 -c double.f -o double.lo
double.f: In subroutine `dtrsyl':
double.f:27942: Internal error: Segmentation fault.


Example 5:
                gcc 2.96, CFLAGS and FFLAGS set to $RPM-OPT-FLAGS
		but -ffast-math removed (this flag has always caused R
		build to fail in the past)
....
gcc -I. -I../../../src/include -I../../../src/include -I/usr/local/include
-DHAVE_CONFIG_H -mieee-fp -D__NO_MATH_INLINES -fPIC  -O3
-fomit-frame-pointer -pipe -mcpu=pentiumpro -march=i586
-fno-strength-reduce -c Lapack.c -o Lapack.lo
g77  -fPIC  -O3 -fomit-frame-pointer -pipe -mcpu=pentiumpro -march=i586
-fno-strength-reduce -c double.f -o double.lo
double.f: In subroutine `dgecon':
double.f:1931: Internal error: Segmentation fault.


Example 6:
		gcc 2.96, $RPM-OPT-FLAGS enabled
....
mcpu=pentiumpro -march=i586 -ffast-math -fno-strength-reduce -c Lapack.c
-o Lapack.lo
g77  -fPIC  -O3 -fomit-frame-pointer -pipe -mcpu=pentiumpro -march=i586
-ffast-math -fno-strength-reduce -c double.f -o double.lo
g77  -fPIC  -O3 -fomit-frame-pointer -pipe -mcpu=pentiumpro -march=i586
-ffast-math -fno-strength-reduce -c cmplx.f -o cmplx.lo
cmplx.f: In subroutine `zbdsqr':
cmplx.f:783: Internal error: Segmentation fault.

Any suggestions ?
