Build from source

[Daniel Monteiro]

Trying to build the last days from source q-x86 / pie-x86 and it always fails!

Tried on clean Linux under ubuntu 18.04 / 20.04 with only build env setup, and it fails always in same line.

Also the intruction on packager over the website its wrong, it points to install xmllin, this package does not exist in ubunto 18.04 or other distro, this binary is found under the package libxml2-utils .

The error that keep me stoping of building:

Someone can point me what could be? Tried all that can remenber and searched with no avail.

Will correct that. Thank you!

According to the log, your OUT_DIR is just empty.
That's very strange... It's the root cause of the error.

Did you follow the build instructions exactly?
Please show the 'printconfig' result after you issued the lunch command.

I feel so dummy, the OUT_DIR its not empty, altough the issue is that, the location of the OUT_DIR, been building android for some time now and you can export the variable of the OUT_DIR as

OUT_DIR_COMMON_BASE use other disk to storage the build files ) and build will follow that location!

It seems android-x86 build process does not follow this across all building, because the variable its indeed picked up from the build, but then it fails during some files building.

Taken from Android Establishing a Build Environment

https://source.android.com/setup/build/initializing#using-a-separate-output-directory

This have been implemented since Android 4.1

Now tried without the OUT_DIR_COMMON_BASE var settled and it build just fine, so the culprit is found.

Thanks for the hint on OUT_DIR, would never tough about that. But you should consider looking at this, since its standard over android building process.

Probably the building process only have this screwed over the kernel building process.

android-x86/kernel/build.config.allmodconfig

L6 :    ${KERNEL_DIR}/scripts/config --file ${OUT_DIR}/.config \
L14:    (cd ${OUT_DIR} && \
L15:     make O=${OUT_DIR} $archsubarch CC=${CC} CROSS_COMPILE=${CROSS_COMPILE} olddefconfig)
