Is there any way to rebuild only changed parts of package with build-package.sh?

[twaik]

Hello.
I want to patch a big project, so building it with build-package.sh takes a while.
And changes are pretty much small so rebuilding the whole project if I change a few lines is not very efficient.
Is there a way to make build-package.sh not clean the build directory and simply make ninja/make and build the deb? Without rebuilding everything?

I know I can use on-device building for this, but this does not seem to be really comfortable to me.
Thank you.

I miss the good ol' days with makepkg --noextract --noprepare 😞

You are the worst man ever, not reading docs of script you have been using for a long period of time.

Actually, I found out myself couple of days ago, but I don't port packages, so never needed to look into it. But there are lot of bugs in build-package.sh, so I don't know if it works properly.

Probably we should add this to build-package.sh's help text because it is not there.

Build a package by creating a .deb file in the debs/ folder.

Available options:
  -a The architecture to build for: aarch64(default), arm, i686, x86_64 or all.
  -d Build with debug symbols.
  -D Build a disabled package in disabled-packages/.
  -f Force build even if package has already been built.
  -F Force build even if package and its dependencies have already been built.
  -i Download and extract dependencies instead of building them.
  -I Download and extract dependencies instead of building them, keep existing /data/data/com.termux/files files.
  -L The package and its dependencies will be based on the same library.
  -q Quiet build.
  -w Install dependencies without version binding.
  -s Skip dependency check.
  -o Specify directory where to put built packages. Default: output/.
  --format Specify package output format (debian, pacman).
  --library Specify library of package (bionic, glibc).

Already did that, will push soon.

I have added a pull request with that change sometime ago.

For some reason mesa package produced with ./build-package.sh -I -f -c mesa is not installable.

Adding rm -rf ${TERMUX_PKG_MASSAGEDIR}/DEBIAN to termux_step_post_make_install fixed the thing, but that is not an option for merging to master.
