“ADOL-C error: Cannot allocate tape buffers!”

This message indicates that the buffer size specified for Adol-C is too high. In your problem directory, edit the hidden file .adolcrc and decrease the buffer sizes. Note that using tape files instead of buffers can cause a significant drop in performance if accessing the files over a network. In this case, try working on a local partition.


We noticed that some antivirus can cause problems during the compilation of the thirdparty softwares for Bocop. In this case, please disable your antivirus check during the installation, and re-enable it once done. Case spotted: Avira under Win7.

The windows package includes precompiled libraries for the ThirdParty softwares Ipopt and Adol-C/ColPack. Source files are also included so that you can rebuild the libraries if you encounter some incompabilities. To do this, simply remove the files in the ‘libs’ folders in ThirdParty/Ipopt and Adolc. The GUI will then rebuild these files automatically (this can take several minutes).

If you already have MinGW installed on your computer you might have GCC > 4.7. In this case you will have to use ADOL-C-5.2.1 instead of ADOL-C-2.5.0. Here is the procedure to follow:
– Download at:
– Extract the archive in /ThirdParty


With gcc 4.8.3 you might have an error during Ipopt build: “don’t have function for random number generator”. This will result later in the error “IpoptApplication.h not found”.

To solve this you have to type the following commands in the terminal:
> cd ThirdParty/Ipopt-3.1*
> ./configure –enable-static –prefix=/ThirdParty/Ipopt-3.1* coin_skip_warn_cxxflags=yes
> make
> make install


If a problem occurs while building IPOPT, please go to the IPOPT directory, and run ./configure with the following options:
* F77=/path/to/your/fortran/compiler
* ADD_FFLAGS=”-O3 -ftree-vectorize -m64″
* ADD_CFLAGS=”-O3 -ftree-vectorize -arch x86_64 -m64″
* ADD_CXXFLAGS=”-O3 -ftree-vectorize -m64″
(replace m64 by m32, and x86_64 by i386 for 32bits architectures)

After configure step, you can run “make” and “make install”.
