After getting a toolchain, you will need to get more
tools & libs:
- * gcc 4.4+
+ * gcc 4.7+
* gperf, bison/flex
- * cmake 2.8.0+
-
- * libusb 1.0+
-
- * SDL SDK 1.2.13+
+ * cmake 2.8.4+
afterwards, simply execute:
include_directories (../include/linux ../include/shared ../include lib include)
add_subdirectory(lib)
add_subdirectory(src)
-
- if (CONFIG_CARL9170FW_BUILD_TOOLS_CARLU)
