Compilation problems

[henrykmichalewski]

On Ubuntu 14.04 I ran into compilation issues with Gflags package. Namely, it seems that automatic update of the Gflags repository fails. I installed separetly Gflags from sources (without problems), but it did not help in the sense that the Makefile still tries to install Gflags on its own and fails.

Could you do the following and let me know if it fixes the problem?

• move to the build directory
• rm -rf external lib include
• make (or ninja) to rebuild

I recently made a distructive update on dreal-deps/gflags repository and I think the old one interfered with the new one.

@henrykmichalewski, I just push a commit 02d385f28193a8513559143326e3d85a8a9fcfbb and I think it fixes the problem. Could you do 'make clean' and rebuild dReal?

[henrykmichalewski]

I did the following steps: removed completely the old version of dreal and cloned again the github repository. I followed the ubuntu installation instructions from the github page

git clone https://github.com/dreal/dreal.git dreal
cd dreal
mkdir -p build/release
cd build/release
cmake -DCMAKE_BUILD_TYPE=RELEASE -DCMAKE_CXX_COMPILER=g++-4.8 -DCMAKE_C_COMPILER=gcc-4.8 ../../src
make

Finally the whole process is still stopping at GFLAGS

Admittedly, if I simply try to use the script build-dreal.sh in the main directory, then it fails on something else (I did not investigate it in details, there are actually many errors).

I'm on it...

One of the problems is https://github.com/gflags/gflags/issues/112. I made a patch on our repository https://github.com/dreal-deps/gflags/commit/28d651ccab0a7b78448585fae89f26ea7846065c

I'm still testing and solving other issues. I'll let you know when everything is working.

[soonhokong]

@henrykmichalewski, could you check out the latest version and test? I've also done it on a fresh Ubuntu-14.04 VM and it worked well there. I also fixed some dependency issues by 84482116c836e428be60d14793c9b026a222b673

dReal compiles and works fine.Thank you!
