CMake Error at Utilities/Sphinx/CMakeLists.txt:52 (message): cmake builds its own manual and man pages with Sphinx, asked for by --sphinx-man and --sphinx-html. python-sphinx is a large Python documentation stack and cmake is wanted here as a build tool. Both flags, and they are bootstrap arguments rather than -D options -- cmake configures itself with its own script before it can run itself. Dropping one leaves the other pulling Sphinx in and the error is identical, which is how a half-fix looks like no fix. --- FR --- CMake Error at Utilities/Sphinx/CMakeLists.txt:52 (message): cmake batit son propre manuel et ses pages de manuel avec Sphinx, reclames par --sphinx-man et --sphinx-html. python-sphinx est une large pile de documentation Python, et cmake est voulu ici comme outil de construction. Les deux drapeaux, et ce sont des arguments d amorcage plutot que des options -D : cmake se configure avec son propre script avant de pouvoir s executer lui-meme. N en retirer qu un laisse l autre tirer Sphinx et l erreur est identique, ce qui donne a une demi-correction l apparence d aucune. Assisted-by: Claude Opus 5

# CMake Error at Source/QtDialog/CMakeLists.txt:33 (message):
|
|
# Error when bootstrapping CMake:
|
|
#
|
|
# cmake-gui is a Qt application. Arch lists qt6-base in makedepends and builds
|
|
# it; this port has no Qt and will not grow one to give a bootstrap a dialog
|
|
# box. Same reasoning as pinentry's Qt front end, and the cost is the same
|
|
# thing: a graphical program nothing here can display.
|
|
#
|
|
# WHY cmake IS IN STAGE 1 AT ALL, since it is worth being clear that this is
|
|
# not scope creep: four PKGBUILDs call cmake directly, and stage 2 rebuilds
|
|
# every package inside a chroot that has to contain the build systems. cmake
|
|
# is a tool the REBUILD needs, not a dependency of anything in the repository
|
|
# -- which is why the dependency resolver never asked for it.
|
|
#
|
|
# --sphinx-man and --sphinx-html stay: sphinx-build is installed, and the man
|
|
# pages are worth having.
|
|
#
|
|
# The makedepends entry goes with the flag. Nothing checks it under --nodeps,
|
|
# but a package declaring a build dependency it does not use is the same
|
|
# untruth as gcc-libs declaring libhwasan -- and leaving it would tell the
|
|
# next reader that Qt was needed here.
