cgen: fix function-like macro '_BIONIC_AVAILABILITY_GUARD' is not defined in termux

[Krchi]

fix compiler error in termux(0.118.0)

I do not get it - currently V works fine on Termux. What problem does this solve?

[Krchi]

does
_BIONIC_AVAILABILITY_GUARD need ndk, and i cant build v

[spytheman]

Sorry, but I already do use Termux on my own phone which is running Android 14 and is RMX3630.
V works there, and I use it ~ once per week. Many other people have used V on Termux too (search the Discord). It even has a dedicated section in the readme, documenting the steps needed to install it there:

pkg install clang libexecinfo libgc libgc-static make git
pkg update
git clone --depth=1 https://github.com/vlang/v
cd v
make
./v symlink

If you have a specific problem with it, please file an issue, describing the actual details, like Termux version, Android level etc.

That:

_BIONIC_AVAILABILITY_GUARD need ndk, and i cant build v

is not enough to understand the issue.

Thanks for the edit of the description.

What is your cc --version ?

[spytheman]

for me, using make:

termux-info shows that mine is 0.118.3, and has TERMUX_APK_RELEASE=GITHUB

Thanks for the edit of the description.

fix compiler error in termux(0.118.0)

make also cant work, because _BIONIC_AVAILABILITY_GUARD is old code, and i had to fix macro in v.c, and #if __BIONIC_AVAILABILITY_GUARD && __BIONIC_AVAILABILITY_GUARD(28) is not robust when macro not defined

[Krchi]

What is your cc --version ?

20.1.7

Have you run pkg install clang libexecinfo libgc libgc-static make git and have you installed Termux from the Google Play store, or from https://github.com/termux/termux-app ?

It seems like I haven't updated in a long time.

Does it still fail (after the update) on the master branch @Krchi ?

it ok after update, may be old ndk version is 27,
but the currcent check is wrong, it should check with two #if or ensure have before use

Thank you @Krchi 🙇🏻 .
Excellent work.
