Hey, thx for your fast answer. I found the mingw's bin. But I don't understand "and prior to that, you should add mingw's bin directory to PATH". What is PATH? How can I add a directory to it? By the way: The "Boost Getting Started guide" was my first attempt. It didn't work for me either.

Hello all,

I have problems with installing Boost. I downloaded boost_1_36_0.zip and extract it to c:\boost\. After that I downloaded boost-jam-3.1.16-1-ntx86(2).zip and extract bjam.exe to c:\boost\boost_1_36_0\.

Now I start cmd and goes to c:\boost\boost_1_36_0\! There I execut bjam with following parameters bjam.exe "-sMINGW_ROOT_DIRECTORY=C:\Dev-Cpp" "-sTOOLS=mingw" install

Please use the instructions from Boost Getting Started guide, as opposed to any third-party docs. In particular, the eventual command like should look line:

bjam.exe toolset=mingw install

and prior to that, you should add mingw's bin directory to PATH.

Thanks for your answer. I regret to ask you agin for help. The instalation started, the directory boost\lib\ was created. But boost\lib keeps empty!!! Before I run bjam with bjam.exe toolset=gcc install I execute the following commands: set INCLUDE=C:\Dev-Cpp\include set INCLUDE=C:\Dev-Cpp\include\c++ set INCLUDE=C:\Dev-Cpp\include\c++\mingw32 set INCLUDE=C:\Dev-Cpp\include\c++\backward set LIB=C:\Dev-Cpp\lib set PATH=%PATH%;C:\Dev-Cpp\bin set PATH=%PATH%;C:\Dev-Cpp\lib\gcc-lib\mingw32\3.2 The result of the installation was: ...failed updating 314 targets... ...skipped 345 targets... ...updated 7134 targets... What am I doing wrong? I included all the directories, that are included in dev-cpp after the instalation.

Well, PATH is the environment variable that tells where to look for binaries. You can use either:

set PATH=<some-dir>;%PATH%

to add elements to it, or the System Setting, though I don't remember exactly what to click there.

After you do that, verify that running "g++" works, then run bjam.

Thanks for your answer.

I regret to ask you agin for help.

The instalation started, the directory boost\lib\ was created. But boost\lib keeps empty!!!

Before I run bjam with bjam.exe toolset=gcc install I execute the following commands: set INCLUDE=C:\Dev-Cpp\include set INCLUDE=C:\Dev-Cpp\include\c++ set INCLUDE=C:\Dev-Cpp\include\c++\mingw32 set INCLUDE=C:\Dev-Cpp\include\c++\backward

Just a guess, but the problem might be related to the fact that you are overwriting the value of INCLUDE with each statement above. Try: set INCLUDE=C:\Dev-Cpp\include;%INCLUDE% set INCLUDE=C:\Dev-Cpp\include\c++;%INCLUDE% set INCLUDE=C:\Dev-Cpp\include\c++\mingw32;%INCLUDE% set INCLUDE=C:\Dev-Cpp\include\c++\backward;%INCLUDE% HTH / Johan
