Hi all,


I need to compile my RedHat Enterprise 4 64bits to install 32bits programs and driver. Thank´s.

And why do you think that the kernel is not compiled to use 32-bit apps???? The supplied Red Hat kernels are compiled to allow running 32-bit applications already, perhaps you are missing the needed 32-bit lib packages to support the 32-bit program(s).

And no you cannot load a 32-bit driver in a 64-bit OS, either find the source for the driver and rebuild or locate the 64-bit driver if possible. If you need help please provide some specifies like which program(s) and or driver(s) you want to install.

what is the name of the 32bits lib package?
The program is labview and the driver is for GPIB(PCI)(National Instrumentation). How I find the source for this driver?How I rebuild this? Thank´s.

Did a bit of looking and it seems that you may need to install the 32-bit and maybe the 64-bit compat-glibc packages, for example;

$ rpm -qa --qf="%{n}-%{v}-%{r}.%{arch}.rpm\n" 'compat*' | sort
compat-db-4.2.52-2.x86_64.rpm
compat-gcc-32-3.2.3-47.3.x86_64.rpm
compat-gcc-32-c++-3.2.3-47.3.x86_64.rpm
compat-glibc-2.3.2-95.30.i386.rpm
compat-glibc-2.3.2-95.30.x86_64.rpm
compat-glibc-headers-2.3.2-95.30.x86_64.rpm
compat-libcom_err-1.0-5.i386.rpm
compat-libcom_err-1.0-5.x86_64.rpm
compat-libgcc-296-2.96-132.7.2.i386.rpm
compat-libstdc++-296-2.96-132.7.2.i386.rpm
compat-libstdc++-33-3.2.3-47.3.i386.rpm
compat-libstdc++-33-3.2.3-47.3.x86_64.rpm
