The result is an overly complex 9*4882a593Smuzhiyunmass of code that does not support cross-compilation in several ways. 10*4882a593Smuzhiyun 11*4882a593SmuzhiyunZip 3.0 has a similar build system, and has as many as 6 patches in 12*4882a593SmuzhiyunBuildroot to cross-compile [0]. UnZip fails at building even with 13*4882a593Smuzhiyunthese patches adapted and a few more on top of them. 14*4882a593Smuzhiyun 15*4882a593SmuzhiyunInstead of tweaking and fixing a huge and complex build system, skip 16*4882a593Smuzhiyunit entirely and add a pretty simple CMakeLists.txt that cross-compiles 17*4882a593Smuzhiyunsmoothly using CMake. It also preserves all of the Buildroot-provided 18*4882a593Smuzhiyunbuild options and flags as the original Makefile does. 19*4882a593Smuzhiyun 20*4882a593Smuzhiyun[0] http://git.buildroot.net/buildroot/tree/package/infozip?id=2015.11-rc3 21*4882a593Smuzhiyun 22*4882a593SmuzhiyunSigned-off-by: Luca Ceresoli <luca@lucaceresoli.net> 23*4882a593Smuzhiyun--- 24*4882a593Smuzhiyun CMakeLists.txt | 17 +++++++++++++++++ 25*4882a593Smuzhiyun 1 file changed, 17 insertions(+) 26*4882a593Smuzhiyun create mode 100644 CMakeLists.txt 27*4882a593Smuzhiyun 28*4882a593Smuzhiyundiff --git a/CMakeLists.txt b/CMakeLists.txt 29*4882a593Smuzhiyunnew file mode 100644 30*4882a593Smuzhiyunindex 0000000..27951b4 31*4882a593Smuzhiyun--- /dev/null 32*4882a593Smuzhiyun+++ b/CMakeLists.txt 33*4882a593Smuzhiyun@@ -0,0 +1,17 @@ 34*4882a593Smuzhiyun+cmake_minimum_required(VERSION 2.8) 35*4882a593Smuzhiyun+INCLUDE(CheckFunctionExists) 36*4882a593Smuzhiyun+ 37*4882a593Smuzhiyun+project(unzip C) 38*4882a593Smuzhiyun+ 39*4882a593Smuzhiyun+CHECK_FUNCTION_EXISTS(lchmod HAVE_LCHMOD) 40*4882a593Smuzhiyun+if(NOT HAVE_LCHMOD) 41*4882a593Smuzhiyun+add_definitions("-DNO_LCHMOD") 42*4882a593Smuzhiyun+endif() 43*4882a593Smuzhiyun+ 44*4882a593Smuzhiyun+set(UNZIP_SOURCES unzip.c crc32.c crypt.c envargs.c explode.c 45*4882a593Smuzhiyun+ extract.c fileio.c globals.c inflate.c list.c match.c process.c 46*4882a593Smuzhiyun+ ttyio.c ubz2err.c unreduce.c unshrink.c zipinfo.c unix/unix.c) 47*4882a593Smuzhiyun+ 48*4882a593Smuzhiyun+include_directories(.) 49*4882a593Smuzhiyun+add_executable(unzip ${UNZIP_SOURCES}) 50*4882a593Smuzhiyun+install(TARGETS unzip DESTINATION bin) 51*4882a593Smuzhiyun-- 52*4882a593Smuzhiyun1.9.1 53*4882a593Smuzhiyun 54
