| Building egcs-1.0.3 |
| |
| Now that egcs is configured, you are ready to build the compiler and |
| runtime libraries. |
| |
| We highly recommend that egcs be built using gnu-make; other versions |
| make work, then again they might not. To be safe build with gnu-make. |
| |
| Building a native compiler |
| |
| For a native build issue the command "make bootstrap". This will build |
| the entire egcs compiler system, which includes the following steps: |
| * Build host tools necessary to build the compiler such as texinfo, |
| bison, gperf. |
| * Build target tools for use by the compiler such as gas, gld, and |
| binutils. |
| * Perform a 3-stage bootstrap of the compiler. |
| * Perform a comparison test of the stage2 and stage3 compilers. |
| * Build runtime libraries using the stage3 compiler from the |
| previous step. |
| |
| If you are short on disk space you might consider "make |
| bootstrap-lean" instead. This is identical to "make bootstrap" except |
| that object files from the stage1 and stage2 of the 3-stage bootstrap |
| of the compiler are deleted as soon as they are no longer needed. |
| |
| Building a cross compiler |
| |
| We recommend reading the [1]crossgcc FAQ for information about |
| building cross compilers. |
| |
| For a cross build, issue the command "make cross", which performs the |
| following steps: |
| * Build host tools necessary to build the compiler such as texinfo, |
| bison, gperf. |
| * Build target tools for use by the compiler such as gas, gld, and |
| binutils. |
| * Build the compiler (single stage only). |
| * Build runtime libraries using the compiler from the previous step. |
| |
| Note that if an error occurs in any step the make process will exit. |
