I am compiling on WinXP using Cygwin's Bash - I compiled 4.1.1 OK but not 4.2.0
(CVS). The makefile works away for a long time and finally stops - unfinished.
What I did to fix it:
After you run the ./configure script there will be a makefile in your build
directory. Open it in wordpad and also open the makefile from your 4.1.1 build
in another wordpad window.
Goto the wordpad with the 4.1.1 Makefile and search for the text
"stage1-start::" . Do the same with the 4.2.0 Makefile. Rename the 4.2.0
"stage?-start::" sections to "Origonal-stage?-start::" and the 4.2.0
"stage?-end::" sections to "Origonal-stage?-end::". Now copy the 4.1.1
"stage?-start::"
and 0 "stage?-end::" sections into the 4.2.0 Makefile at each appropriate
place. Hope that is clear.
You _could_ also fixup "stageprofile-start::" while you are there, I did in my
Makefile but have not yet typed "make stageprofile" to test if profiled
building is working in 4.2.0.
Don't forget that 4.2.0 has an extra directory that is not in 4.1.1
(libdecnumber) so in each of the "stage?-start/end" sections you will need to
add a couple of lines for the libdecnumber directory.
I found that the 4.1.1 Makefile worked perfectly (for 4.1.1) and adding those
sections into the 4.2.0 Makefile caused it to work correctly. Prior to making
this fix I was unable to get make to build properly. It kept trying to coping
the directories into each other instead of renaming them and shuffling them (if
that is how it could best be described).
The 4.2.0 Makefile says "We use mv on platforms where symlinks to directories
do not work or are not reliable." I've not got to running down why the
configure script chose the "mv method" but it breaks on Windows XP (for me).
Other people claim to have done a cygwin build (with far fewer things enabled)
but they might not have built it on Windows XP (where "ln" works fine and "mv"
copies into the directory instead of overwriting the directory - it is not
"dos" "copy").
If the maintainers where to use the 4.1.1 release version "style of operation"
for the stages of the 4.2.0 (CVS) make then it would work properly (for me and
I imagine for others too - not a lot of WinXP builds reported).
Here is a tiny portion of one stage of the 4.2.0 makefile to further
demonstrate:
