Compile static library for QNX 7.0.0 #2162

Closed SebastianKunz closed 2 years ago

SebastianKunz commented 2 years ago

Im interested in using spdlog with qnx 7.0.0. Currently I'm using the header only version, which works great, except that my compile time is now +10 seconds. Thats why I checked out the static library approach, but I am stuck. Here is what I did. I compiled spdlog like described in the readme. Then qnx screamed at me, because of an unrecognized-relocation-0x2a-in-section-text-5565, and this stackoverflow article explains why. So I tried to use the QNX qcc compiler, which cmake does not know. I also looked at #738, but it didnt help me.

Has anyone had any chance at compiling spdlog with qnx 700 and can explain to me how to reproduce? I am still a newbie regarding qnx, so please bear with me.

Thanks

@SebastianKunz Sid you find a solution?

SebastianKunz commented 2 years ago

Sadly no.

gabime commented 2 years ago

closing. this platform not supported by spdlog. If you happen find a solution please update here anyway.

Just got this working on QNX 7.1 by setting the following in my CMakeLists.txt before adding spdlog:

add_compile_definitions(_QNX_SOURCE)

See http://www.qnx.com/developers/docs/7.0.0/index.html#com.qnx.doc.neutrino.prog/topic/devel_ConformingToStandards.html for more info.

这是有效的，此外也可以这么写（-std=gnu++17不是必须的）-D_QNX_SOURCE： _This is valid, and can also be written like this (-std=gnu++17 is not required) -D_QNX_SOURCE:_

set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=gnu++17 -D_QNX_SOURCE")

编译参数配置，经测试，无法指定C++标准，否则无法识别boost 详情参考 http://www.qnx.com/developers/docs/7.0.0/#com.qnx.doc.neutrino.utilities/topic/q/qcc.html <-std=language> 此选项还有其他变体可以启用特定于供应商的编译器扩展： gnu99 、 gnu11 、 gnu++98 、 gnu++11 、 gnu++14 和 gnu++17 。 如果您使用这些变体，则会自动定义 _QNX_SOURCE，并启用编译器的一些其他非标准功能；请参阅海湾合作委员会文档。 如果不指定 -std，则 C 和 C++ 的默认值分别为 gnu11 和 gnu++14 。 参见 http://www.qnx.com/developers/docs/7.0.0/index.html#com.qnx.doc.neutrino.prog/topic/devel_ConformingToStandards.html 如果要符合给定的语言标准，可以对 qcc 使用 -std=language 选项。 此选项可能会导致头文件的某些部分被省略，这可能会导致问题，因为由 POSIX 定义的函数或特定于 QNX Neutrino 的函数不会被定义。
