显示xcode版本
xcode-select -p
显示gcc版本
gcc --version
切换xcode版本
sudo xcode-select -s /Applications/Xcode113.app/Contents/Developer
装多个xcode新的会把旧的环境变量覆盖 用新的gcc就不对了
会有很多奇怪的编译错误
切回去就好了 用哪个切哪个
https://docs.unrealengine.com/en-US/Platforms/Linux/GettingStarted/index.html
切完点这个
GenerateProjectFiles.command
遇到这样一个error
Command XcodeBuild.sh failed to exit code 6
link failed
-weak_libray file not found
这个error吧。似乎是直接点run导致的
先点product-build
success之后再点
product-run
就成功了
另一个error
ShaderCompileWorker[1347:13092] flock failed to lock maps file: errno = 35
有个messagebox说路径太长不合法 点确认就可以了 这个error就能过了
还遇到这样一个error
unable to execute command: posix_spawn failed: Argument list too long
DerivedDataBackendGraph
这货我又遇到了 和放的路径深没有关系
(这种方式测过没用
project.build.cs
bLegacyPublicIncludePaths = false）
clang: error: unable to execute command: posix_spawn failed: Argument list too long
那些都没变 只是xcode换了换 但11.3之前用过也是可以的
debugGame的ios包 换成debug能过这个bug。。。。。good luck
像这个bug
Some people get the following error when building a bigger component using Clang:
clang: error: unable to execute command: posix_spawn failed: Argument list too long
clang: error: linker command failed due to signal (use -v to see invocation)
It looks like Clang expands the @argfile before calling the linker and ends up passing everything to the linker as a single command line.
就是这个bug
I appear to be experiencing a similar issue. The linking command using clang is 50k characters due to the presence of many object files and fails when called from Gradle. However, calling clang++.exe @argumentsFile succeeds.
