I am trying to cross-compile the latest pycurl package, but the problem may apply to earlier versions as well. My googling has revealed this package not to be very cross-compile friendly.
First of, I am using buildroot and the buildroot toolchain( uclibc latest version) for the cross compilation.
The package uses gentargets to build, as it was not written for autotargets. And the build command simply calls setup.py:
define PYCURL_BUILD_CMDS
(cd $(@D);\
CC="$(TARGET_CC)"\
LD="$(TARGET_LD)"\
$(HOST_DIR)/usr/bin/python setup.py build\
--curl-config=$(STAGING_DIR)/usr/bin/curl-config)
endef
The problem is that after the object files are built, the build script decides to use the host compiler insted of the target compiler:
building object files:

If you'we ever cross compiled this package or have any idea about the problem I'm facing I'd appreciate the help.
