I am building boost on my windows using mingw-4.8.1 and have a few targets which failed. My Problem is that, I do not know which specific targets failed and which were skipped.
Is there a way to list the failed/skipped targets after the build is completed?
Here the console output:
...failed updating 20 targets...
...skipped 28 targets...
...updated 5789 targets...
Commands used after downloading a unzipping boost:
bootstrap
once b2.exe is built. I execute the following command in cmd
b2 -j4 --build-dir=build toolset=gcc --build-type=complete --stagedir=C:\SW\Boost -sNO_BZIP2=1
System: Windows 7 ( intel i5 vPro)
Compiler: gcc (mingw 4.8.1)
Boost: boost 1.61.0
So, a little bit of more research resulted in the following.
One can get the build configuration and other build output using
b2 [options]
b2 --help reveals the options that can be used. I used the following approaches to diagnose exactly which targets were failing or getting skipped.
Approach 1
As suggested by @JanHenke in comments, I ran the same command
b2 -j4 --build-dir=build toolset=gcc --build-type=complete --stagedir=C:\SW\Boost -sNO_BZIP2=1
(as mentioned in question) again.
Result: All tragets that are already built are skipped and only failed ones are shown.
Problem: If there are many targets which failed then this just floods the console and it is difficult to find out what is going on.
Approach 2
Run the command (see 1) and select all from the command prompt using right mouse click, and then click gain to copy and paste it in a text editor so that is searchable.
Result: Usable insights can be drawn by searching for failed or error keywords
Problem: Still not the optimal way as not all the info is vailable on the current cmd window.
Approach 3
Not Done as for me 2. worked, but should surely work
Create a batchfile where in, the command is written and all that is printed on the cmd window, gets logged in a text file using the > or >> operators.
Result: Will be the best way (known to me till now) to know which exact targets are getting failed and a proper diagnostic action can be taken.
PS: I found that the there is a bug when trying to build serialization library with MinGW. Below the error I am facing and a link to boost forum which talks about the same error.

More info Reference1 and Reference2.
Sadly have not found a solution for it yet. Also, it is not the scope of this question.
