Re: Compilation fails with "skipping incompatible .../libstdc++ .. "

You need yo install the 32bit libraries.

Hi,

I would like to install android-x86 on my Centrino convertible laptop.
I already tried a nightly build iso, which seemed to be rather old. But sometimes it worked more or less.

That's why I am now trying to compile on my own. Started on Windows but moved to Linux when it complained about a the filesystem not being case sensitive.
I already solved a ton of problems, but now I haven't got any idea left.

I am building on a Mint KDE 64 bit linux. And this seems to be the problem:

Why ist HOST_ARCH=x86?
I already tried to install ia86-libs, but this did not help.

Could you please give a hint?

thanks,

Dear JPT,

You're missing libstdc++ package (esp. -dev package if you're on debian) and
possible it's ia32 version.

Best regards,

I already installed ia32-libs. This did not help.
Today I tried lib32stdc++6, no change...
According to the message it did not find the newly installed library.
So the log is still the same.
Do I have to feed the library location into the build script? Or should I create a symlink somewhere?

[JPT]

Now it works.
Found a solution which said:
cd /usr/lib32
ln -s libstdc++.so.6 libstdc++.so

I don't like this, because this is the first time I have to add links in the library folders. But it works.
Is there any "clean" solution to this problem?

Thanks!

That is the standard way that libraries are set up to point at the latest incarnation and is normally done when the library is installed/updated by the installer - so it is a 'clean' solution.
