`fatal error: sys/_timespec.h: No such file or directory` with v3.7.0-rc2 #75319

Closed 0x6e closed 3 months ago

I've started a discussion regarding this issue, but received no feedback so far.

Describe the bug Compiling my application with v3.7.0-rc2 fails to build:

compilation terminated.

To Reproduce I wasn't able to find any existing samples that set CONFIG_POSIX_API=y which also failed to build.

[!NOTE] Edited by @ycsin 

west build -b native_sim -p auto samples/hello_world/ -- -DCONFIG_CPP=y -DCONFIG_POSIX_API=y -DCONFIG_STD_CPP20=y -DCONFIG_REQUIRES_FULL_LIBCPP=y

Expected behavior The applicaiton should compile.

Impact Cannot update to v3.7.0-rc2 (or future versions).

Environment (please complete the following information):

Additional context Git bisect shows the breakage is introduced by the following change: 487a8756c32320f0f1fbe1fbe342849ef89e7440 posix: eventfd: fix dependency cycle between net and posix.

Hi @0x6e! We appreciate you submitting your first issue for our open-source project. 🌟

Even though I'm a bot, I can assure you that the whole community is genuinely grateful for your time and effort. 🤖💙

ycsin commented 4 months ago

Would you be able to share the full compile log & autoconf.h?

EDIT: nvm, I managed to reproduce this

west build -b native_sim -p auto zephyr/samples/hello_world/ -- -DCONFIG_CPP=y -DCONFIG_POSIX_API=y -DCONFIG_STD_CPP20=y -DCONFIG_REQUIRES_FULL_LIBCPP=y
ycsin commented 4 months ago

I'm not sure what is the root cause yet, it compiles fine if this line is disabled:

https://github.com/zephyrproject-rtos/zephyr/blob/6700a154be3ca29be50fb4f1e35d899de69be5ca/include/zephyr/net/socket.h#L1416

Can't really understand the magic here, cc @jukkar @cfriedt @rlubos

cfriedt commented 4 months ago

@ycsin - can you make a PR?

I think there likely won't be a problem if that line is removed

0x6e commented 4 months ago

Removing the specified line allows my project to build.

aescolar commented 4 months ago

Sorry to join the party late, I forgot about this issue. The issue here is that that kconfig combination leads to a non allowed kconfig setup. (POSIX_API enabled but using the host glibc . Due to CONFIG_REQUIRES_FULL_LIBCPP=y setting CONFIG_PICOLIBC_SUPPORTED to n). Note that even if the liked PR avoids the build error, you are very likely to end up with a not working executable, or one which is doing quite weird things.

0x6e commented 4 months ago

Wouldn't it be better to report this as an unsupported configuration then, rather just failing to compile with some obscure message?

aescolar commented 4 months ago

Wouldn't it be better to report this as an unsupported configuration then, rather just failing to compile with some obscure message?

Of course

0x6e commented 4 months ago

Is there an appropriate place to add such a check, and a place to add a test for this?

0x6e commented 4 months ago

I'm a bit frustrated that this has been closed as completed. The compiler error has just changed now that the #75351 has been merged:

[90/117] Building C object zephyr/kernel/CMakeFiles/kernel.dir/work.c.obj
ninja: build stopped: subcommand failed.

I've tried to various configuration options, but as far as I can tell CONFIG_REQUIRES_FULL_LIBCPP=y and CONFIG_POSIX_API=y are incompatible options. Is that really the case? That seems to be quite a regression considering that this configuration previously worked...

@0x6e - it's unfortunately still necessary to workaround the existing dependency cycle between networking and posix (CONFIG_NET_SOCKETS_POSIX_NAMES, deprecated) and also avoid pulling in host headers when building for native_sim.

Fix is just going through CI.

Thank you very much @cfriedt your changes work for me.
