Setting the GCC ELF-compatible compiler version to use<br />
You can control the GNU compiler collection (GCC) version to use by setting a<br />
variable in the maketpf configuration file.<br />
Before you begin<br />
Your administrator must have customized the tpftools/include_ztpf/<br />
maketpf_rules_cfg_REDHAT file to support more than one version of the GCC<br />
compiler.<br />
Procedure<br />
1. In the maketpf configuration file (maketpf.cfg), define the compiler to use by<br />
setting the MAKE<strong>TPF</strong>_COMPILER variable to REDHAT (MAKE<strong>TPF</strong>_COMPILER :=<br />
REDHAT). REDHAT is the default.<br />
2. Define the compiler version to use by setting the <strong>TPF</strong>GCC_VERSION variable.<br />
For example, <strong>TPF</strong>GCC_VERSION := 41 or <strong>TPF</strong>GCC_VERSION := 46. The default is<br />
determined by querying the version that is found in the PATH environment<br />
variable.<br />
