Breakpoint in C++ class constructor is never reached
Netherlands	2007-10-26 06:45:18
Hello, I have a C++ application built for Solaris Sun 5.8 with gcc 3.2.x and SUN linker. When i put a breakpoint in the constructor/destructor of my C++ classes it's never reached. A breakpoint set in any other method of the same class gets hit with no problems. I've found some info that this was a known issue in the 6.3 release. But i'm using 6.7 and i still see the same problem. Is there any solution/workaround known for this problem? Thanks in advance! Dmitri. --------- Ñàìûé ñîäåðæàòåëüíûé ïîðòàë î òóðèçìå è îòäûõå â Áåëàðóñè http://belarustourism.by/ Ãîðîäà Áåëàðóñè http://belarustouris m.by/cities/ Ðàçâëå÷åíèÿ, àðõèòåêòóðà, ãîñòèíèöû, áàçû îòäûõà, íàöèîíàëüíûå ïàðêè.

Sorry i'm not really familiar with GDB release scheme... What is HEAD and where can i find it? One more question: are there any plans to solved this issue in the 6.7 release?

Unfortunately i can't do anything with one of the latest snapshots. I've donwloaded gdb-weekly-6.7.50_20071023. config goes ok (./configure --enable-gcc --prefix=/scratch/debugger). make gives the following error: make: Fatal error in reader: Makefile, line 63: Unexpected end of line seen Current working directory /usr/local/gdb-6.7.5/gdb-6.7.50_20071023/libdecnumber * Error code 1 make: Fatal error: Command failed for target `all-libdecnumber' Current working directory /usr/local/gdb-6.7.5/gdb-6.7.50_20071023 * Error code 1 make: Fatal error: Command failed for target `all' Is it a known issue? Should somebody submit a bug report for that? i can build the same version of gdb with gmake (i know this is not the idea... i just tried to see if it works and it does!). However when i run the newly built latest version of gdb with my C++ application i got "Symbol format `elf32-sparc' unknown.". It is solved in 6.7.1 but probably is not synchronized yet with the latest...

Should somebody submit a bug report for that? Oh dear. GCC requires GNU make, but GDB is not supposed to, I don't think. This is a new problem. > i can build the same version of gdb with gmake (i know this is not the idea... > i just tried to see if it works and it does!).

That fix should be in HEAD, but I didn't commit it until the same day as that snapshot; you'll need to get a later one. -- Daniel Jacobowitz CodeSourcery

I regularly build GDB with OpenBSD make, so yes this is new (and I'd very much appreciate it if it got fixed).

I've asked Thiago to take a look at it. The problem arose because we imported libdecnumber from GCC - unlike GDB, GCC requires GNU make. -- Daniel Jacobowitz CodeSourcery

I just posted a patch to fix this. Sorry for the delay, it took me some time to determine if I had copyright assignment to contribute to GCC. I tested the change with NetBSD's make, so I think the GNUisms are gone. If this is not enough to fix your build problems, please let me know. I can send you off-list a regenerated configure script if you want to test the patch and don't have autoconf 2.59 handy. -- []'s Thiago Jung Bauermann Software Engineer IBM Linux Technology Center
