Cannot compile to Android due to Clang errors

[emanrdesu]

I ran
./configure Calculator android verbose
make clean
make

and it says Clang cannot create executables
is there any way I can make it use gcc if Clang keeps not working?

Related, but how can I make it compile with android 9 - api 28, it says it switches to api 24 as a warning

We switched from GCC to Clang due GCC being phased out for Android development - see #266. It is interesting to note that you have issues with it though as we check for the tool to be present. Can you post the actual error message here or as a gist? Also what platform are you on and what version of Clang are you using?

For the unrelated question, I'd like to ask you to file a separate issue. Not all APIs are complete [can't tell if 28 is on top of my head] and thus tools have to be found by going to earlier versions - see android/host_linux#L42 or the macOS equivalent.

here's output of make: https://pastebin.com/M4qpcgS2
here's config.log: https://pastebin.com/YC551JCN
here's output of clang -v: https://pastebin.com/ujY2UxUU

I'm using Arch Linux.

The /home/gabriel/.cache/lambdanative/android-api28/android-ndk-r13b-arm-24-toolchain/bin/clang38: error while loading shared libraries: libncurses.so.5: cannot open shared object file: No such file or directory piece looks suspicious to me - is your compiler broken or not linked correctly?

[mgorges]

Also can you build the app on your native platform?

[emanrdesu]

I can build the app in linux mode yes.

[mgorges]

Okay, but that is likely done with GCC, so something in clang is broken (as it doesn't seem linked completely according to the error reported above). - If libncurses is not installed then install it and try again?

[emanrdesu]

I tried reinstalling ncurses and clang, but neither works

[mgorges]

Not ncurses program but the library libncurses5. The other problem could be a 32bit/64bit mismatch somewhere in your system.

[emanrdesu]

It seems that for Arch, libncurses comes with the ncurses
I'm installing compiling clang version 5 right now maybe will work

[mgorges]

Your solution might be discussed here: android/ndk#574, which refers to an issue with clang assuming ncurses 5 being available, while Arch Linux only has version 6; maybe try adding ncurses5-compat-libs first?
