Re: [fpc-devel] fpcmkcfg invocation for two versions (linux)
thank you, but my question was more about where to put fpc.cfg so that both versions can use it properly, or, if that is not possible, where to stuff different fpc.cfg's for the same purpose? and what would be the basepath in either case? Normally, if you install both versions at the same location, you don't need two fpc.cfg files. Inside the fpc.cfg you can use macro's so that the the compiler searches for the right units (ppu's). This is done by fpcmkcfg by default. (Or samplecfg which is a wrapper around fpcmkcfg) Overall the proces is quite simple: install fpc version A. Rename the compiler-executable from ie. ppcx64 to ppcx64_2_6_4. Then install fpc version b. Now you can select which version you want to use by calling the compiler using different names. (ppcx64 and ppcx64_2_6_4). This works perfectly if you use an IDE like Lazarus, in which you can simply select which compiler-executable to use. If you want to use 'fpc' to call the compiler, you need some additional tricks. But to answer your question: you can place a fpc.cfg in the same location as the executable. If you place the executables of both compiler-versions in a different directory, they can both have their own fpc.cfg. (You can use the -va compiler option to see which fpc.cfg is actually used) My current setup is that I have fpc-trunk installed in my home-directory. (I use 'make install PREFIX=~/fpc') And I have added ~/fpc/bin/x86_64 to my path. And I have a fpc.cfg in ~/fpc/bin/x86_64. But I also have fpc 2.6.4 installed, the version provided by my Linux-distribution. If I need the original/latest release I use the full path to the compiler, or rename ~/fpc to ~/fpc_. In short: there are a lot of configurations possible, and everyone can decide what's the best setup for his/her needs.

Re: [fpc-devel] Building 2.7.1 on current Raspbian fails
Don't know why you have this problem with wheezy, but can confirm I'm running rpi jessie, and the 'sudo' sequence above works for me ok ie does 70Mbyte download installs fpc with no errors. Haven't really tested it, but help says it is 2.6.2 -8 rpil+b2 2014/7/21 for arm. john On 21 October 2014 12:58, Paul Michell p...@michellcomputing.co.uk wrote: On Tuesday 21 Oct 2014 09:31:42 peter green wrote: Ok, i've just uploaded 2.6.4 https://archive.raspbian.org/raspbian/pool/main/f/fpc/ Thank you, how am I best to install this?

Raspbian jessie should have 2.6.4 soon (it's already in raspbian jessie-staging..). Raspbian wheezy will be staying with 2.6.0 So it would seem FPC is currently broken on stable Raspbian which is a pity. It's fine on plain raspbian, unfortunately it seems that the raspberry pi foundation are shipping a newer version of binutils which conflicts with the fpc packaging from wheezy. Since the breakage is not related to plain raspbian I won't be putting a fix for this in the main raspbian repository but I intend to set up a repository for fixes to raspberry pi foundation screwups soon and i'll post a url for that when it's ready. ___ fpc-devel maillist - fpc-devel@lists.freepascal.org http://lists.freepascal.org/cgi-bin/mailman/listinfo/fpc-devel
[fpc-devel] Dumping the syntax tree
Hi all, I wonder where in the FPC compilation flow would be a good spot to dump the parsed syntax tree of a source? Here's why I'm asking. For a while now, I've been struggling to adapt a bunch of Pascal code to various mobile platforms. It's been painful. The code itself is pretty conservative feature-wise, almost KR C-like (except sets and ansistrings). I wonder if I could slap together a quick and dirty Pascal-to-C converter just for this codebase to work, but I'd rather reuse the existing parsing logic. So if anyone could point me at a spot in the FPC source where the source tree is more or less ready, that's be nice. Thanks in advance. ___ fpc-devel maillist - fpc-devel@lists.freepascal.org http://lists.freepascal.org/cgi-bin/mailman/listinfo/fpc-devel
