Cross Compilation on Windows for Android fails
ikeen0807 opened this issue · 0 comments
For some reason I cannot get my project to build openssl-sys. The reason for that are unescaped backslashes in the corresponding Makefile generated in the process. I have no clue on how to fix this. The makefile cannot find the clang.exe inside of the NDK folder, since it includes unescaped backslashes it thinks that the following is the path to my clang.exe:
.../AppData/Local/Android/Sdk/ndk/25.1.8937393/toolchains/llvm/prebuilt/windows-x86_64binclang.exe
I also already spotted the mistake in the Makefile, which is making the build fail:
CROSS_COMPILE=
CC=$(CROSS_COMPILE)C:/Users/kema/AppData/Local/Android/Sdk/ndk/25.1.8937393/toolchains/llvm/prebuilt/windows-x86_64\bin\clang.exe
CXX=$(CROSS_COMPILE)g++
CPPFLAGS=-DANDROID
CFLAGS=-Wall -O3 -fomit-frame-pointer --target=i686-linux-android24 -mstackrealign -O2 -ffunction-sections -fdata-sections -fPIC -gdwarf-2 -fno-omit-frame-pointer -m32
CXXFLAGS=-Wall -O3 --target=i686-linux-android24 -mstackrealign -O2 -ffunction-sections -fdata-sections -fPIC -gdwarf-2 -fno-omit-frame-pointer -m32
As seen above it tries to access the clang.exe via backslashes, which is probably because I am on windows. But I think its expecting unix-like paths.
For further background information in what kind of context this occurs. This is a Tauri 2.0 App and this occurs in the buidling process. Therfore I am using the command "npm run tauri android dev", where I cannot just pass variables into in order to influence the building process for openssl-sys.
I declared the openssl-sys dependency like this: openssl-sys = { version = "0.9.102", features = ["vendored"]}.
This is my configdata.pm dump:
