Re: [Lazarus] Install Lazarus on Mac OSX Catalina
I'm not on Catalina yet, but I tried building a cross compiler for Cocoa with 64bit OSX earlier today and failed. It seems that Lazarus on OSX can't see a 64bit compiler if you use cross install. What I thought would work was: make all make install INSTALL_PREFIX=`pwd` crossinstall OS_TARGET=darwin CPU_TARGET=x86_64 INSTALL_PREFIX=`pwd` Then I copied ./lib/version/ppc and ./lib/version/ppcross to ./bin/ and created a valid ./bin/fpc.cfg Then I built Lazarus. I tried building with widgetset as Cocoa and CPU are x86_64 but I could not get the make to work. Then I tried building Lazarus normally, and changing a new project to use 64bit and Lazarus would have none of it, arguing that the current compiler does not support x86_64. Eventually I gave up on building it myself and used fpcudeluxe instead to install a Cocoa 64bit compiler and Lazarus. If anyone has any tips on how to manually create a FPC and Lazarus that support compilation to both 32 and 64bit, or even just a 64bit Cocoa only version, I'd appreciate any help. I could probably figure it out, but it would save me a lot of time in re-compiling. Thanks -- ___ lazarus mailing list lazarus@lists.lazarus-ide.org https://lists.lazarus-ide.org/listinfo/lazarus
[Lazarus] autocomplete a lookup field in Dbgrid?
I have a a dataset with a lookup field. I edit it with a dbgrid. The grid correctly uses a picklist for that field, but I couldn't find an easy way to autocomplete it (i.e. allow the user to type the first few characters of the value to select an entry). The problem seems to be that the picklist field uses a TPickListCellEditor which derives from a TCustomComboBox that doesn't implement such functionality (it does but only to set the text in case it's a csDropDownList, it doesn't set the selected item). I see that a TDBLookupCombobox supposedly implements autocomplete (I saw some forum post when they say it's problematic, don't know if it has been solved now), but I cannot use it since I'm setting two fields, not one. Any idea?

Re: [Lazarus] Install Lazarus on Mac OSX Catalina
Some experiences having just tried moving my main application to Cocoa without upgrading to Catalina. The results look very promising, and my application looks usable, though I didn't try running 64 bit Lazarus. i can make the following observations: 1. For 32 bit compilation you need to avoid upgrading to the latest xcode; 10.3 looks like the last one that has the required 32 bit components. Older versions of xcode can be downloaded from the Apple developer site, and at least some co-existence is possible. (I ended up with 10.3 installed in my home directory.) 2. I typically compile with all range checks on, and this triggered some range checks in the widegt set - see https://bugs.freepascal.org/view.php?id=36171 3. Fixed point fonts can have non-integer spacings; I was using CarbonWidgetSet.SetTextFractional(Canvas, False) but this does not seem to be available under Cocoa so I had to specify the spacing in ExtTextOut. 4. Polyline, at least for large numbers of points. seems to be 10 times slower than under Carbon, which is itself slower than other OS's 5. For compiling trunk FPC I use: FPC=~/fpc/bootstrap/ppc386 make distclean DEBUG=1 install PREFIX=~/usr CPU_SOURCE=i386 OPT=-Fl/Users/me/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/usr/lib to compile a 32 bit compiler to ~/usr starting from a 32 bit compiler and FPC=~/fpc/bootstrap/ppcx64 make distclean DEBUG=1 install PREFIX=~/usr64 CPU_SOURCE=x86_64 OPT=-Fl/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/usr/lib to compile a 64 bit compiler to ~/usr64 starting from a 64 bit compiler. I add symbolic links in the two directories: for f in usr usr64 ; do cd ~/$f/bin if [ ! -L ppc386 ] ; then ln -s ~/usr/lib/fpc/$VER/ppc386 ; fi if [ ! -L ppcx64 ] ; then ln -s ~/usr64/lib/fpc/$VER/ppcx64 ; fi done and with this setup lazarus can pick up the two compilers.

[Lazarus] Testers wanted: FpDebug on Linux and Windows
It is time to get some feedback on how FpDebug behaves in the wild. If you want to test it, you need: - Lazarus 2.1 revision 62049 (dated 13 Oct 2019) or higher/later - Fpc any version that above Lazarus works with. If you use FPC trunk, you should aim for revision 43183 or higher. earlier trunk will cause bad results inspecting bitpacked arrays 3.0.4 is fine 3.2 may depend on what gets merged when, and FpDebug may need amendments if certain fpc fixes are merged. As for what to expect: https://wiki.lazarus.freepascal.org/FpDebug When reporting back: - Your Lazarus and FPC version/revision. - Your OS (with version and 32 or 64 bit) - Your IDE is 32 or 64 bit - Your FPC is 32 or 64 bit - Your target app is 32 or 64 bit (and indicate if it was cross compiled, by an FPC with different bitness) - In case something failed, log output of (or preferably, a reproducible testcase) lazarus.exe --debug-log=file --log-enable=DBG_STATE,DBG_DATA_MONITORS,DBG_ERRORS,DBG_VERBOSE,DBG_WARNINGS,DBG_BREAKPOINTS,DBG_FPDEBUG_VERBOSE,FPDBG_BREAKPOINT_ERRORS,FPDBG_BREAKPOINTS Thank you -- ___ lazarus mailing list lazarus@lists.lazarus-ide.org https://lists.lazarus-ide.org/listinfo/lazarus
[Lazarus] Feedback about GDB on Windows
To all who - use Lazarus on Windows (any version of Lazarus 2.0 or 2.1) - use or have tried GDB 8.2 (for 64bit users also GDB 7.7 or 8.1) from https://sourceforge.net/projects/lazarus/files/Lazarus%20Windows%2032%20bits/Alternative%20GDB/ https://sourceforge.net/projects/lazarus/files/Lazarus%20Windows%2064%20bits/Alternative%20GDB/ What is your experience with GDB 8.2 (7.7/8.1)?

Any degradations you noticed? - Your Lazarus and FPC version/revision. - Your OS (with version and 32 or 64 bit) - Your IDE is 32 or 64 bit - Your FPC is 32 or 64 bit - Your target app is 32 or 64 bit (and indicate if it was cross compiled, by an FPC with different bitness) Thank you -- ___ lazarus mailing list lazarus@lists.lazarus-ide.org https://lists.lazarus-ide.org/listinfo/lazarus

Forgot to mention: Which Dwarf version do you use? 32bit users, please ensure you switch to Dwarf. Testing with Stabs (fpc -g or -gs / the default for 32 bit) is pointless.
