Hi, I'm facing a problem with Bjam under Cygwin. My directory tree looks as
follows:
src/
- Jamroot
+ libFTree/
- Jamfile
- ... (source files)
+ Tests/
+ Test02/
- Jamfile
- ... (source files)
When I use Bjam to build libFTree DLL, this is what cygcheck sees in it:
Found: c:\FORWARE\PortableForware\win32\FTree.dll
c:\FORWARE\PortableForware\win32\FTree.dll
C:\cygwin\bin\cygwin1.dll
C:\WINDOWS\system32\ADVAPI32.DLL
C:\WINDOWS\system32\ntdll.dll
C:\WINDOWS\system32\KERNEL32.dll
C:\WINDOWS\system32\RPCRT4.dll
Error: could not find cyggraph-4.dll
Error: could not find cyggvc-4.dll
However the command line that I get from BJAM (-d+2 option) looks like this:
gcc.link.dll bin/gcc-3.4.4/debug/libFTree.dll.a
"g++" -L"/usr/local/lib"

There is no reference to any of cyggraph-4.dll or cyggvc-4.dll import libs,
which by the way are Graphviz libs that I used a few days ago and now I've
removed from Cygwin and from Jamfiles.
If I use a regular makefile to build a static library, this is what cygcheck
sees:
$ cygcheck ./libFTree.a
.\libFTree.a
In this case, the command to build the static library looks like this:
ar ru libFTree.a ftreeGeneric/FTree.o ftreeGeneric/FRaw.o
ftreeGeneric/FTreeList
.o ftreeAutoGenerated/FTreeGenerated.o ftreeHardware/FHardware.o
ftreeHardware/F

ynthesis.o ftreeUtils/FApplication.o ftreeUtils/FTreeHandler.o
ftreeUtils/FGarba
geCollector.o ftreeUtils/FIRer.o ftreeUtils/FBoostGraph.o
ar: creating libFTree.a
After linking the executable with the static library, cygcheck sees this:
$ cygcheck ./main.exe
.\main.exe
C:\cygwin\bin\cygwin1.dll
C:\WINDOWS\system32\ADVAPI32.DLL
C:\WINDOWS\system32\ntdll.dll
C:\WINDOWS\system32\KERNEL32.dll
C:\WINDOWS\system32\RPCRT4.dll
May this be a bug in BJAM? Maybe it holds a cache of dependencies, since
some time ago I used Graphviz libraries... Any ideas?
Regards.
