Ninja build error

[hayleyyan]

I'm following the development documentation, and has successfully finish the development environment setup. I am running into an issue in OpenBMC Hello World in SDK, particularly in the steps to run (https://github.com/openbmc/docs/blob/master/development/sdk-hello-world.md#clone-and-build-a-repo):

meson build
ninja -C build 

After running ninja -C build it returns the follow:

I have tried installing cereal and cmake but neither seem to resolve the error.

Any suggestions on how I can resolve this error?

[williamspatrick]

None of those look like warnings. Is there more to the build log?

Please upload text to a service like gist.github.com (or paste here) rather than attempting to take screenshots.

Here's the full output when i run ninja -C build https://gist.github.com/hayleyyan/4f352a884c4cc45eeee1afb0f4b4da04

It seems like the only warning is this:

/root/sdk/romulus-2022-06-06/sysroots/arm1176jzs-openbmc-linux-gnueabi/usr/include/features.h:412:4: error: #warning _FORTIFY_SOURCE requires compiling with optimization (-O) [-Werror=cpp]
  412 | #  warning _FORTIFY_SOURCE requires compiling with optimization (-O)
      |    ^~~~~~~

I'm not sure why that is present since it appears that the compiler call includes -O2: arm-openbmc-linux-gnueabi-g++ -marm -mcpu=arm1176jz-s -fstack-protector-strong -O2 -D_FORTIFY_SOURCE=2 -Wformat -Wformat-security -Werror=format-security --sysroot=/root/sdk/romulus-2022-06-06/sysroots/arm1176jzs-openbmc-linux-gnueabi -Iphosphor-hypervisor-state-manager.p -I. -I.. -fdiagnostics-color=always -D_FILE_OFFSET_BITS=64 -Wall -Winvalid-pch -Wnon-virtual-dtor -Wextra -Wpedantic -Werror -std=c++20 -O0 -g -DENABLE_WARM_REBOOT -DBOOST_ASIO_DISABLE_THREADS -DBOOST_ALL_NO_LIB -DBOOST_SYSTEM_NO_DEPRECATED -DBOOST_ERROR_CODE_HEADER_ONLY -DBOOST_COROUTINES_NO_DEPRECATION_WARNING -MD -MQ phosphor-hypervisor-state-manager.p/hypervisor_state_manager_main.cpp.o -MF phosphor-hypervisor-state-manager.p/hypervisor_state_manager_main.cpp.o.d -o phosphor-hypervisor-state-manager.p/hypervisor_state_manager_main.cpp.o -c ../hypervisor_state_manager_main.cpp

@geissonator Any ideas on this? I don't see anything obviously wrong from the phosphor-state-manager's meson.build.

@hayleyyan In the short term you could probably get rid of these two lines in the meson.build:

        'warning_level=3',
        'werror=true',

https://github.com/openbmc/phosphor-state-manager/blob/master/meson.build#L5

[williamspatrick]

Oh... There is a -O2 and then later there is a -O0. Any ideas where the -O0 is coming from? Have you set any CFLAGS or CXXFLAGS environment variables? Can you also check if the SDK set any of them?

[hayleyyan]

I didn't set any of those environment variables but it seems the SDK have set them to the following:

echo $CFLAGS
-O2 -pipe -g -feliminate-unused-debug-types

echo $CXXFLAGS
-O2 -pipe -g -feliminate-unused-debug-types

[manojkiraneda]

@hayleyyan which build type are u trying to build ? wonder if it is coming due to meson's default build debug which comes with -O0

As phosphor-state-manager does not implicitly defaulted the build type to debugoptimized(comes with -O2) , it might be taking the meson's default build type debug (comes with -O0), but the SDK what you would have sourced in implicitly would have added an -O2 in the CXXFLAGS environmental variable which is why you probably see both optimization's in the build log.

Can you try building with meson build -Dbuildtype=debugoptimized to see if the error goes away ?

[hayleyyan]

@manikandan-e i'm building on romulus. Here's the output with meson build -Dbuildtype=debugoptimized

Seems good now... There is just a warning about an unused variable.

When i'm trying to do the next command in Load the Application Into QEMU, it's returning the following:

Here's all the files I have under build:

Seems like some files were built but some weren't?

Unless you fixed this, then the phosphor-bmc-state-manager seemed to fail. Should be a pretty straight-forward fix for you...
