Building boost

I'm trying to install the boost libraries for mingw. I'm running bjam like so:

Code:

---

bjam -sTOOLS=mingw --prefix=c:\MinGW\Boost --without-python install

---

The installation main folder is located in C:\MinGW\Boost_1_33_1\
This is also from where I am running bjam.

The environment variables for the MinGW toolset have been set as requested:

Code:

---

MINGW_BIN_DIRECTORY=C:\MinGW\bin\
MINGW_INCLUDE_DIRECTORY=C:\MinGW\include\
MINGW_ROOT_DIRECTORY=C:\MinGW\
MINGW_STDLIB_DIRECTORY=C:\MinGW\lib\

---

However, I get the following error on all calls to g++ (here an example)

Code:

---

...failed gcc-C++-action bin\boost\libs\regex\build\boost_regex.dll\mingw\release\winstances.obj...
gcc-C++-action bin\boost\libs\regex\build\boost_regex.dll\mingw\release\usinstances.obj
g++: no input files

---

What am I doing wrong?

I'm sure that this page will help you.

While it doesn't appear to make a real difference, I would do it like that and in that order.

Those are the environment vars I need to setup. I had followed that step before using bjam.

I've downloaded the boost_1_33_1.exe file from sourceforge and installed it to "C:\MinGW\Boost_1_33_1\". Then downloaded the bjam executable and set those environment variables.

When I run bjam, I get that error on every call to g++.

This is one example of what bjam is requesting from g++:

"C:\MinGW\bin\g++" -c -Wall -ftemplate-depth-255 -DNDEBUG -DNDEBUG -DBOOST_ALL_DYN_LINK=1 -DUSE_DATE_TIME_PRE_1_33_FACET_
IO -O3 -finline-functions -Wno-inline -mthreads -mno-cygwin -I"bin\boost\libs\date_time\build" -I "C:\MinGW\include\" -I "C:\b
oost_1_33_1" -o "bin\boost\libs\date_time\build\boost_date_time.dl l\mingw\release\threading-multi\greg_month.obj" "C:\boost_1_3
3_1\libs\date_time\build\../src/gregorian/greg_month.cpp"

Perhaps MingW can't handle the mix of forward and back slashes in the input file? You could try that out on the command line.

It was a good tip. But unfortunately just tested it. It allows that mixture.

That -mno-cygwin command line option is worrying me some. And I can't find any reference to it in the GCC manual. But from other -mno types found in the manual it seems to be disabling compilation for cywgin. Which is just fine.

Is that correct, and does that file exist? You said previously that: "The installation main folder is located in C:\MinGW\Boost_1_33_1\"...

Disclaimer: Never touched Boost. (Thought about it.)

Yes. It is correct. I re-unpacked later on with the zip distribution to test it (maybe the exe distribution was broken). At that attempt, I done it to that location.

EDIT: I'm taking this to the boost mailing list as soon as the webpage where I can subscribe stops exhibiting a bug. If it was not for the excellent review of the community at general, at this point I would think Boost is poorly implemented.

To close on this issue (in case anyone is wondering or does a search on the forums in the future) the solution to the problem was just found.

The environment variables should have been declared with forward slashes. It's building correctly now.

My thank you to ChaosEngine and Leo Domery
