在Termux中使用GCC编译器？ -- termux 领域 android 相关 的问题

I don't like the default C compiler clang provided by Termux. Is there a way I can get GNU GCC in my Termux environment?

Another way to get gcc would be to add the community repo hosted by its-pointless at https://github.com/its-pointless/its-pointless.github.io. Sources are (more or less) available at https://github.com/its-pointless/gcc_termux.

Other popular packages available includes numpy and scipy.

More information about this and other community repositories can be found in the termux wiki.

To add this particular repository to your termux environment, run:

# Get some needed tools. coreutils for mkdir command, gnugp for the signing key, and apt-transport-https to actually connect to the repo apt-get update apt-get  --assume-yes upgrade  apt-get  --assume-yes install coreutils gnupg2 apt-transport-https wget  # Make the sources.list.d directory mkdir $PREFIX/etc/apt/sources.list.d # Write the needed source file - Added Missing "> character on line below echo "deb [trusted=yes] https://its-pointless.github.io/files/ termux extras" > $PREFIX/etc/apt/sources.list.d/pointless.list # Download signing key from https://its-pointless.github.io/pointless.gpg  wget https://its-pointless.github.io/pointless.gpg apt-key add pointless.gpg # Update apt apt update

This is a very interesting solution.

First download GCC for C4droid from Google Play.

Go find its apk under /data/app/com.n0n3m4.gcc4droid-#, take the APK and extract /assets/gcc.zip. Now extract gcc.zip to

/data/data/com.termux/files/usr/libexec 

Apply chmod -R 644 to the whole folder and chmod -R 755 to ARCH/bin, bin and libexec. Link gcc programs to $PREFIX/bin and you'll be able to use GCC instead of Clang. Remember to add -pie when compiling executables.

Install Arch Linux in Termux PRoot to get a full Linux development environment. See https://sdrausty.github.io/TermuxArch/docs/install for installation instructions. Use pacman -S base base-devel to install the developer's environment which includes GCC.

I created termux repo with gcc 10.2.0, there how to install https://cctools.info/index.php/Termux_repository_with_cctools_packages_(gcc_with_fortran_support_etc)

Add cctools packages public key:

wget -O - https://cctools.info/public.key | apt-key add - 

Create a new repository list:

echo "deb https://cctools.info termux cctools" > $PREFIX/etc/apt/sources.list.d/cctools.list 

Update packages lists:

apt update 

Install the package gcc-cctools(it will install binutils-cctools automatically):

apt install gcc-cctools 

Install the NDK package for your android architecture, use the latest one, for example for aarch64:

apt install ndk-sysroot-cctools-api-26-aarch64 

To show all ndk sysroots for aarch64:

apt search ndk-sysroot-cctools | grep aarch64 

Add directory with new compilers to PATH:

export PATH=$PREFIX/../cctools-toolchain/bin:$PATH 

Check it:

gcc -v
