I got it to successfully link by adding some lines to the target.mk file (attached below). I then got some errors / warnings regarding the stdlib. I fixed that by appending CC_CXX_WARN_STRICT= to the make command.

However, I still cannot compile the program as I get an error that ld.lib.so is missing even though it is listed as a build dependency in my run file (see attached log file).

I want to use the ext4.h header to open files on the ext4 filesystem (i.e. with ext4_fopen) as I am reworking the snapshotting capability of the project I am working on. The hello world file was just a test to see if everything (primarily the run file) would compile successfully.

 Hello,

I want to test out lwext4, however when I try to compile it, I get an error that ext4.h was not found. I have attached my main.cc, target.mkhttp://target.mk and squid.run files below. The platform I am using is x86_64 linux. If anyone knows has any idea how to link the lwext4 library please let me know, as I could not find much information online.

Best, Rumen

Not sure what you want to achieve. Accessing ext4 file systems? Probably a bad idea in Genode/Linux.

Michael

Sorry didn’t read your run file. Looks fine even though, why include the header in a hello world file?

Replace Main xxx ... to Main xxx(env); No warnings!

Here is a version of you main.cc:

//#include <ext4.h> #include <base/component.h> #include <base/log.h>

namespace Squid { struct Main; };

struct Squid::Main { Genode::Env &_env;

Main(Genode::Env &env) : _env(env) { Genode::log("hello from squid"); } }; using namespace Squid; void Component::construct(Genode::Env &env) { Main xxx = Main(env);

}

I am not a c++ wizard , but the above compiles if you add "base" to LIBS in target.mk. Notice the ';' after Struct Main. You will get a warning that "xxx" is set but not used. Good luck! Michael
