Hi, I'm in the process of testing the drm-next-4.7 branch from the FreeBSDDesktop github repository on several computers. As I want to avoid building world on every machine, I decided to set up a dedicated build machine running FreeBSD 11.0-STABLE. The plan was to build world, kernel and some parts of the ports tree with poudriere, and then generate FreeBSD release images and a pkgng repository for binary packages.
I was able to build both the world and the kernel successfully. I was also able to generate working install images with the make release command. However, it seems that the whole build process skips building the base versions of llvm39 and clang: as a consequence, all systems installed from the release images lack a compiler. Installing the new world and kernel on the build machine does not install llvm39: instead, llvm38 is left untouched, until flagged obsolete by the make remove-old-libs command, and deleted. Does anybody know why make avoids building base llvm39 as a bootstrap compiler even while the current base version is llvm38 ? Is there a way to force the build of base llvm and clang ? I do not use any src.conf or make.conf file. I read the src.conf(5) man page and tried to pass custom flags to make (like WITH_CLANG, WITH_CLANG_BOOTSTRAP, WITH_CLANG_FULL), without any success. Here is how to reproduce: 1. Install FreeBSD 11.0-RELEASE or a snapshot of 12.0-CURRENT with default options. I tried the following with both versions and base llvm was not built in both case. 2. Install the devel/git package with pkg. 3. Clone the github repository to /usr/src. 4. Try to build everything: # cd /usr/src/ # make buildworld buildkernel 5. The build stops immediately because make cannot find llvm39. Here is the error message: "You need to install devel/llvm39 to build or set XCC" That error is new to me: I never saw it when I ran make buildworld in previous releases. As a workaround, install devel/llvm39, or run make with explicit environment variables: # make XCC=clang XCXX=clang++ XCPP=clang-cpp buildworld buildkernel llvm39 will not be built whatever workaround you chose. 5. After the build finishes, make a release: # cd /usr/src/release # make XCC=clang XCXX=clang++ XCPP=clang-cpp release WITH_DVD=1 6. Install the release to another computer, or install the new world and kernel on the current machine as you would normally do, with mergemaster and make remove-old / make remove-old-libs. 7. Boot the new install or the new kernel, then run: # cc -v No compiler found. Thanks a lot for your help!
