make px4fmu-v2_default does not work on Windows

[johnnyfisma]

Second time setting up a Windows machine to build. Having difficulty with

make px4fmu-v2_default

It built px4io-v2_default with no issues. Then, it had issues with MavLink it seems. Error was

src/modules/mavlink/CMakeFiles/git_mavlink_v2.dir/build.make:56 "target pattern contains no '%'

Googling this and looking at the build.make file, I found that line 56 had this:

src/modules/mavlink/CMakeFiles/git_mavlink_v2: src/modules/mavlink/git_init_C:_Firmware_git_Firmware_mavlink_include_mavlink_v2_0.stamp

and when I replaced the 'C:' with just 'C' it got past that line, but then failed on another with C:. So, for that file, I replaced all C:_ (and did 1 by 1 to watch out for issues) and this build worked no problem (I was a bit surprised the my changes stayed put as I thought it would auto-generate, but sometimes I'm lucky).

So, like I said, that got me through that build. I got the message

Linking CXX executable ../../nuttx_px4fmu-v2_default.elf

However, I then get a few issues with "ld.exe" that

address 0x81001e0 of nuttx_px4fmu-v2_default.elf section '__param" is not within region "flash"

This might be beyond my ability to figure out. Perhaps my need to change the size of my flash in the compiler/linker settings? Any help would be much appreciated.

Also, I'd be interested in helping make the above issues go away with the C:

If someone has ideas on how I can do it, I don't mind trying again. I am currently looking into abandoning Windows building, which is probably the recommended approach, but I think it is nice to continue to support all 3 main OSs if possible.

Found an answer to my final question. Simpler than I expected. Found this link:

http://discuss.px4.io/t/px4-build-firmware-error/630/3

However, it still does seem that there is something wrong with the Cmake settings with that C: issue, and yes, everytime I clean, it results in that same error, but the fix seems like it works everytime, so should be okay.

Closing this as I found the answer.
