cppcm-reload-all yields cryptic error about "flymake Makefile"

[ghost]

it emits an annoying warning message everytime its run even though I have (setq cppcm-write-flymake-makefile nil) in my .emacs, either that or the message is wrong.

[redguardtoo]

what message? you want me suppress the message?

[ghost]

(message "Failed to create Makefile for flymake. Continue anyway.")))

Not sure why I even see it flashing sometimes, but I don't think it's actually tied to flymake particularly. Guess it's a relic from before cppcm supported so many diff packages.

[redguardtoo]

got.

I adjusted the wording of warning message and suppress it by default.

fixed at 6d5da7d more log code. suppress warning (Chen Bin)

But can you use cpputil-cmake successfully?

The reason you see the warning message is because somethings happens, you need compile and create the executable successfully for at least once.

I have compiled successfully but it still flashes occasionally. If it's a real error maybe it shouldn't be supressed but only needs to have the message made more accurate.

Whether it works? I actually don't know. All things other then irony were already manually setup by my .emacs previously. And with irony It doesn't seem to register the build/.json file, which was the reason I installed it. I submitted https://github.com/Sarcasm/irony-mode/pull/237 to do just that in irony itself.

The reason I'm seeing this error may be that, well, my project looks like this:

build/ # cdb here
src/
vendor/foo1/CMakeLists.txt  # 3rd party, without cdb
vendor/foo2/CMakeLists.txt # ...

and I'd like the cdb to be loaded fo code I'm editing in src/. But, it looks like cppcm sees the CMakeLists.txt projects under vendor/, finds there's no cdb there and errors without adding the one that does exist.

[redguardtoo]

then how you compile the code in src/? unless there is one CMakeLists.txt in src, my plugin won't work.

[ghost]

sources in src/ build in /build. But I keep 3rd party libs under vendor/ and build them there straight from tarball/git. If they do not create a cdb by default, it isn't there.

unless there is one CMakeLists.txt in src, my plugin won't work.

exactly.

[redguardtoo]

there must be some CMakeLists.txt in in parent of src/, or else cpputils-cmake will not work

[ghost]

Oh, there is (corrected):

CMakeLists.txt
build/ # cdb here
src/
vendor/foo1/CMakeLists.txt  # 3rd party, without cdb
vendor/foo2/CMakeLists.txt # ...

but afaict it still doesn't work, instead I get the cryptic warning message about "flymake makefile".
