Can't compile without mesos headers installed in system root

[bretthoerner]

Compilation seems to assume I have mesos headers installed in /usr/local/include, is it possible to compile with mesos installed elsewhere? This may be more of a Go problem than a mesos-go one, but the folks in #mesos asked me to make a ticket for now.

$ go get github.com/mesosphere/mesos-go/example_framework
# github.com/mesosphere/mesos-go/mesos
.go/src/github.com/mesosphere/mesos-go/mesos/executor_driver.cpp:5:30: fatal error: mesos/executor.hpp: No such file or directory
 #include <mesos/executor.hpp>
                              ^
compilation terminated.

I guess I should note I've tried a bunch of things to put the includes on a path (from env vars, go cmd args, to using the cgo comment pragmas) with no luck so far.

Hi @bretthoerner
This is an interesting question! Thanks for reporting! So have you tried to set CGO_CFLAGS already?
Hmm, I will try to do some experiments over the weekend. And give you some feedback.

At the meanwhile, I recommend you use the 'refactor' branch under 'github.com/mesosphere/mesos-go' if you haven't yet.
Which replaced those function pointer stuffs with interfaces.(Though it won't solve your problem).

The native go binding is under development, hopefully we can get rid of the libmesos and cgo soon.

Thanks!

Hi @bretthoerner
By doing go build -n, I found that the include path is not shown when compiling the cpp files. Then I noticed that when compiling the cpp files, it will use CXXFLAGS instead of CFLAGS.
So I fixed the cgo comment pragmas to replace the CFLAGS with CXXFLAGS at the latest master branch.

Now you can either change the #cgo CXXFLAGS to include the path to your installed mesos or change the environment CGO_CXXFLAGS.

Hope that can help!

@bretthoerner Did you get this working?

[bretthoerner]

I never did, I used Python and Scala for what I needed at the time.

I run into this issue too but was able to solve it by setting some env variable (from this other ticket:
#40 )

now that I read it again, I ended up doing make install to copy the files to the system folders, but even after that , I had to set this up:

LD_LIBRARY_PATH=/usr/local/lib/

in case it helps here.
