Hi,
I have statically linked the DynaLoader with plperl.so and modified plperl.c
so that plperl functions executes do not execute within the 'safe
compartment'.
plperl.c have been changed as follows:
extern void boot_Opcode _((CV * cv));
extern void boot_SPI _((CV * cv));
extern void boot_DynaLoader _((CV* cv)); <------ Added
static void plperl_init_shared_libs(void) {
char *file = __FILE__;
dXSUB_SYS; <------- Added
newXS("Opcode::bootstrap", boot_Opcode, file);
newXS("SPI::bootstrap", boot_SPI, file);
newXS("DynaLoader::boot_DynaLoader", boot_DynaLoader, file);
<---added
}
I then compile plperl.c as follows:
gcc -o blib/arch/auto/plperl/plperl.so -shared -L/usr/local/lib plperl.o
eloglvl.o SPI.o /usr/lib/perl5/5.00503/i586-linux/auto/Opcode/Opcode.so
-L/usr/lib/perl5/5.00503/i586-linux/CORE -lperl `perl -MExtUtils::Embed -e
ccopts -e ldopts`
When I try to import a perl module that relies on a C module I get the
following error message:
ERROR: creation of function failed : Can't load
'/usr/lib/perl5/site_perl/5.005/i586-linux/auto/Pg/Pg.so' for module
Pg: /usr/lib/perl5/site_perl/5.005/i586-linux/auto/Pg/Pg.so: undefined
symbol: PL_sv_undef at /usr/lib/perl5/5.00503/i586-linux/DynaLoader.pm
line 169.
at /caseTracking/packages/SP.pm line 7 BEGIN failed--compilation aborted
at /caseTracking/packages/SP.pm line 7.
BEGIN failed--compilation aborted at (eval 1) line 2.
Any ideas?
Any help is highly appreciated :)
Regards
Ragnar
