I'm having another of my periodic sessions building on minority architectures, I've been rather off this for several months due to various issues- mostly blown computers- at this end.

Running on Debian "Sqeeze" for SPARC, trunk fails if I tell it to add debugging capability to the FP IDE. Building with

make GDB_V607=1 OPT='-V2.6.4 -O- -gl' all

in multiple places I note

fpmake.pp(49) Warning: "crtbegin.o" not found, this will probably cause a linking failure
fpmake.pp(49) Warning: "crtend.o" not found, this will probably cause a linking failure

and

Warning: Unable to determine the libgcc path.

although things generally continue until I get to

If I build with NOGDB=1 then things are generally OK. 2.6.4 built with libgdb, 2.6.2 and 2.6.0 failed (OK without debugger), older versions generally OK. I'm not at this point able to say which versions I've exercised the debugger with, above is build only.

I can live without a debugger, all I'm aiming for at the moment is to have a version of FPC which will work with a fairly recent Lazarus so that I can publish some stuff I've been working on.

Install the libc-(devel) package. And your message is not completely clear, does it compile without gdb?

See also the Lazarus-FAQ.

(textmode IDE also requires libc via ncurses)

Hi Mark,

did you try to generate the libraries needed
to compile FP IDE with GDB support by
using the script in fpcsrc/packages/gdbint/gen-gdblib-inc.sh ?

If you have a build directory of a certain GDB version (let's say 7.8.1 as an example), simply copy the script over to build-gdb-7.8.1/gdb, and run it locally.

This script tries to determine all the libraries needed and generates a second script called copy-libs.sh
that you should call in turn, with a simple arg, the target directory, for example, ./copy-libs.sh ~/pas/libgdb-7.8.1

After that,
using
make -C ./packages/gdbint GDBLIBDIR=~/pas/libgdb-7.8.1 followed by
make -C ide GDBLIBDIR=~/pas/libgdb-7.8.1
should makes the things much easier.

One caveat is to avoid system installed libraries to be installed instead of the ones inside this directory. On systems on which I got this problem, I had to manually remove all lines {$librarypath XXX}
where XXX resolved to /usr/lib or /lib

In the hope this will help,

Pierre Muller

It compiles without gdb and appears to run. There are sufficient libraries etc. installed that 2.6.4 compiles and runs, although as I said I've not exercised the debugger.

I'd note that 2.7.1 installation still ignores e.g. INSTALL_BINDIR=/usr/local/bin/fpc.d/2.7.1 and insists on clobbering anything in /usr/local/bin, hence the fpc binary from trunk has overwritten the one from 2.6.4 which IMO should not be allowed to happen.

Up to date URL please? The version I see is dated 2010 and this is a new problem: 2.6.4 builds and so did 2.7.1 around [checks] 26319 i.e. about a year ago.

Thanks Pierre, I'll investigate. OTOH the existing GDB 6.7.1 libraries appear sufficient for 2.2.4 through 2.4.4 and for 2.6.4, all on the same system without any underlying adjustments.

I've found where we discussed this before, about August 2013. Part of the solution at the time was to use -Xd but...

The problem is that there's now a -Xd being put in the internal command line, without a -Fl for the location of libgcc.a since it's no longer being picked up from fpc.cfg.

If I add an explicit -Fl/usr/lib/gcc/sparc-linux-gnu/4.4 (or whatever) to match libgcc.a then fp builds and runs with libgcc, although I've not tested this aggressively. There was an outdated reference to 4.3.2 in fpc.cfg which had been moved around between several generations of machines, this could have affected some earlier builds.

Is there a more appropriate way of doing this than using OPT=-Fl..., and is having a fixed path for libgcc in fpc.cfg still appropriate?

Noting that the makefile is able to work around the case where it can't find libgdb, could something similar be done for libgcc? In other words, a stern warning that something's not right without screwing the entire build?

I notice that on at least some systems (not limited to SPARC) the libgcc path in /etc/fpc.cfg is derived from the gcc version info even if this doesn't match what's on disc, e.g. something like ...linux-gnu/4.3.2 rather than ...linux-gnu/4.3

Hi Mark,

This should not matter if you use the script I was talking about, because GDB compilation also required libgcc, so that it should be inside the generated gdblib.inc

Yes, see above.

I must confess that I don't even know how this is done...

Pierre
