Subject: [PATCH] Add a CMakeFile.txt to ease cross-compilation
|
||
|
|
|
||
|
|
Info-ZIP's UnZip 6.0 has a complex, hand-crafted Makefile with a
|
||
|
|
companion configure script which try to support an extremely wide
|
||
|
|
range of UNIX-like operating systems. The result is an overly complex
|
||
|
|
mass of code that does not support cross-compilation in several ways.
|
||
|
|
|
||
|
|
Zip 3.0 has a similar build system, and has as many as 6 patches in
|
||
|
|
Buildroot to cross-compile [0]. UnZip fails at building even with
|
||
|
|
these patches adapted and a few more on top of them.
|
||
|
|
|
||
|
|
Instead of tweaking and fixing a huge and complex build system, skip
|
||
|
|
it entirely and add a pretty simple CMakeLists.txt that cross-compiles
|
||
|
|
smoothly using CMake. It also preserves all of the Buildroot-provided
|
||
|
|
build options and flags as the original Makefile does.
