src-cross.tar.bz2
b. Unpack the source files to the root directory. Enter the following commands:
cd /ztpf/tpfcross
tar -xjf /home/downloads/src-cross.tar.bz2
After you complete this step, the /ztpf/tpfcross directory contains a
subdirectory named ./src-cross.
4. Build the compiler:
a. Enter the following command from the /ztpf/tpfcross/build directory to
configure the compiler:
/ztpf/tpfcross/src-cross/configure --target=s390x-ibm-tpf
--with-sysroot=/ztpf/tpfcross/sys-root --prefix=/ztpf/tpfcross/install
--program-prefix=tpf- --enable-languages=c,c++
Note: After configure command processing is complete, if you determine
that you made an error or want to change something (for example,
the installation path), you can enter the rm -rf * command from your
build directory (for example, /ztpf/tpfcross/build) and repeat step
4a.
b. Enter the following command from the /ztpf/tpfcross/build directory to
build the compiler:
make
c. Enter the following command from the /ztpf/tpfcross/build directory to
install the compiler:
make install
5. Complete post-build setup and verification:
a. Update (or create) the path variable and environment variables TPF_X_GCC
and TPF_X_LIBS by using an editor to update a profile file (such as
.bash_profile or /etc/profile.local) or by using the command prompt.
For example, enter the following commands if you are using the GCC 4.1.2
compiler:
export PATH=/ztpf/tpfcross/install/bin:${PATH}
export TPF_X_GCC=/ztpf/tpfcross/install/lib/gcc/s390x-ibm-tpf/4.1.2/include
export TPF_X_LIBS=/ztpf/tpfcross/install/lib/gcc/s390x-ibm-tpf/4.1.2
export TPF_INFO=/ztpf/tpfcross/install/share/info
export INFOPATH=$TPF_INFO:$INFOPATH
If you are using the GCC 4.6.3 compiler, enter the following lines into your
.bash_profile file:
export PATH=/ztpf/tpfcross/install/bin:${PATH}
export TPF_X_GCC=/ztpf/tpfcross/install/lib/gcc/s390x-ibm-tpf/4.6.3/include
export TPF_X_LIBS=/ztpf/tpfcross/install/lib/gcc/s390x-ibm-tpf/4.6.3
export TPF_INFO=/ztpf/tpfcross/install/share/info
export INFOPATH=$TPF_INFO:$INFOPATH
b. Optional: To offer a choice of GCC compiler versions to application
programmers, customize the tpftools/include_ztpf/
maketpf_rules_cfg_REDHAT file to set four environment variables to define
the installation location for the supported levels of the compiler:
