I want to import source code of Lineage OS to Android studio, for that I am executing below commands
source build/envsetup.sh
then I am executing below command
make idegen && development/tools/idegen/idegen.sh
After executing the above command, I am getting below error

Does anyone have an idea, how to resolve this issue, thanks

I had the same error after following the LOS instructions for using Android Studio. I fixed it by lunching my lineage project:
source build/envsetup.sh
lunch lineage_XYZ-eng
make idegen && development/tools/idegen/idegen.sh
"lineage_XYZ-eng" is defined in my vendorsetup.sh at the root of my LOS device tree.

I ran into this issue as well. I found the solution here:
https://patchwork.kernel.org/patch/10780137/
It is not the same code but the problem is the exact same problem.
The issue is that the command is expecting to inherit file descriptors from previous commands, but by default in make this does not happen. So you need to add the '+' to that line in the edk2 makefile Here is the patch I used to get it to work:

It seems m4 is not installed on your system. If you're running Ubuntu, execute the following command:
sudo apt-get install m4

I have no idea about this.It's looks like there are some disabled modules.How can I handle it? I just want to build aosp and import into Intellij Idea to read some java codes.

Try using Ubuntu 14.04 LTS. I had the same error when trying to compile using Ubuntu 16.04 LTS.

It seems export FORCE_BUILD_LLVM_COMPONENTS=true gets you past that...

AOSP Build error: EXECUTABLES/iw_intermediates/version.c

I've made a AOSP build 7.1.1 couple of days ago and it works well. Today I decided to make a clean build (make clean) and start working on it. After that when I'm trying to compile by make otapackage after some time it gives me below error.

#### make failed to build some targets (01:39:34 (hh:mm:ss)) ####
Everytime, its the same. Any solution ?

Its failing when it is trying to check the git version number.
Inside external/iw/version.sh, it is failing when it gets to:
descr=$(git describe --match=v*):
if [ -d .git ] && head=`git rev-parse --verify HEAD 2>/dev/null`; then
git update-index --refresh --unmerged > /dev/null
descr=$(git describe --match=v*)
# on git builds check that the version number above
# is correct...
[ "${descr%%-*}" = "v$VERSION" ] || exit 2
v="${descr#v}"
if git diff-index --name-only HEAD | read dummy ; then
v="$v"-dirty
fi
else
v="$VERSION"
fi
echo '#include "iw.h"' > "$OUT"
echo "const char iw_version[] = \"$v\";" >> "$OUT"
I had the same problem and there is two ways to go about it:
You can comment out everything except v="$VERSION" and the last two
echo lines.But this is a temporary fix.
Another way to solve this is by doing a repo sync before you execute make. I fixed it by simply doing a repo sync and that updated and
fixed everything for me.
