Greetings.
I have a situation with mumble where the build is breaking on armel
architecture. Upstream has identified that this bug is due to the mumble
"link" plugin containing atomic memory operations. I would like to
conditionally patch the source plugins/CMakeLists.txt file based on
architecutre to not build that one plugin for armel. CDBS apparently has a
way of doing this [1] and I would like to find a solution for doing this
with debhelper. I've been searching and haven't found anything quite
fitting.
Can the patched code just look like:
#ifdef __ARMEL__
// Patched code
#else
// original code with atomic memory ops
#endif
Thank you. From this good hint I found an additional [1] piece that may
get the rest of the way
[And, ironic that this particular post on stackoverflow only received
downvotes.]
----------------------
# Store in CMAKE_DEB_HOST_ARCH var the current build architecture
# (Note: See link [2] below for details for this section)
execute_process(COMMAND
dpkg-architecture
-qDEB_HOST_ARCH
OUTPUT_VARIABLE
CMAKE_DEB_HOST_ARCH
OUTPUT_STRIP_TRAILING_WHITESPACE
)
#And use that information later in CMakeLists
if(${CMAKE_DEB_HOST_ARCH} MATCHES "armhf")
...
elseif(${CMAKE_DEB_HOST_ARCH} MATCHES "i386")
...
else()
...
endif()
----------------------
Looking at the manpage for dpkg-architecture, the variable I may want to
conditionally build upon might be DEB_TARGET_ARCH rather than DEB_HOST_ARCH.
