DualLaz
Two simultaneous Lazarus copies operational in Linux 64 bit
Typically, you have a primary install via fpcUP in ~/development.
But you also want a secondary test version in /workdir/LazB independently, possibly for release testing of Lazarus ver. 1.4
Windows users, see Multiple Lazarus install info.
Here is a run-through to achieve that. Let's assume:
- We use the Linux distro: mint 17.1 KDE 64 bit of 2015 (Kubuntu should work too, I guess)
- primary Lazarus resides in /home/you/development installed via fpcUP
- secondary Lazarus will reside at /workDIR/LazB
- no other Lazarus installed via a debian-package installer or whatever, which could interfere somehow (e.g. /usr/local/lib/fpc - so we delete it )
- /home/you below refers to your ~ aka home-directory aka $HOME aka /home/michael or whatever name you chose.
By default, Lazarus uses ~/development/config_lazarus/ as the primary-config-path
We will override that:
In ~ create two shell scripts : runL1.sh and runL2.sh containing
#!/bin/sh /home/you/development/lazarus/startlazarus --primary-config-path=~/.config_lazarus_1st
and
#!/bin/sh /workDIR/LazCC/laz/startlazarus --primary-config-path=~/.config_lazarus_2nd
respectively. Use an explorer like dolphin etc. or type sth. like sudo mkdir /workDIR/LazB and chown to make it accessible to you as a non-root user.
Upon executing runL1.sh a path setting screen will pop up. There we choose
/home/you/development/fpc/bin/x86_64-linux/fpc.sh
as the compiler. Do not choose
/home/you/development/fpc/bin/x86_64-linux/fpc
because it will give you run time errors aplenty (system.ppu not found etc.).
fpc.sh contains
#!/bin/sh # This script starts the fpc compiler installed by fpcup # and ignores any system-wide fpc.cfg files # Note: maintained by fpcup; do not edit directly, your edits will be lost. /home/you/development/fpc/bin/x86_64-linux/fpc -n @/home/you/development/fpc/bin/x86_64-linux/fpc.cfg "$@"
and will obviously be path-adapted for the secondary Lazarus. This is done automatically by fpcUP. We'll run it via fpcupGUI, which is contained in the source zip-archive of fpcUP. Compile and run it with a prior Lazarus install you made.
upon running abovementioned runL2.sh we should complete the path setup in the popup window according to the below pic:
... and we're done. We have 2 independent Lazarusses on disk ! Now you can repeat the routine n times with new paths, if you so desire.
for copying, here is the settingsCC.ini:
; example settings for fpcup CC ver ; use e.g. fpcup --inifile=settingsCC.ini --inisection=generalCC ; to compile with the options specified in that section [generalCC] [generalCC] installdir=/workDIR/LazCC primary-config-path=/workDIR/LazCC/pcp4fup fpcdir=/workDIR/LazCC/fpc lazdir=/workDIR/LazCC/laz lazlinkname=/workDIR/LazCC/lazrunner.sh lclplatform=gtk2 ; Full FPC+Lazarus download & compile ; Here use FPC trunk instead of the version tagged "default fixes" fpcurl=http://svn.freepascal.org/svn/fpc/trunk ; Compiles with debug options: fpcopt="-g -gl -O1" lazopt="-g -gl -O1" ; Use our own names to avoid overwiting defaults fpcuplinkname=fpcuptrunkdebug lazlinkname=lazarus_fpctrunk ; Keeps changes you made to the svn checkout: keeplocalchanges=true ; You can enable/disable modules specified in fpcup.ini: anchordocking=0
