You could also use the fppdf code included with FPC and generate PDFs of any size (you don't have to stick to standard paper sizes). Not sure if PDF will suit your needs, but you will end up with a very portable format that scales. Secondly, you could also use AGG-Pas. It's fully implemented in Object Pascal so is very portable (I've used it on RPi, Windows, Linux, FreeBSD and OSX). It is a anti-alias sub-pixel framework with configurable rendering pipelines. You can use the "raw" API to get the most flexibility, or use the easier 2D unit but reduces functionality and flexibility. The latest code is included with the fpGUI project, but still 100% stand-alone - no dependencies on fpGUI at all. It also comes with a huge about of demos so show off the features. Original AGG-Pas website. But as I said, the code in fpGUI's repo is newer with multiple bug fixes and improvements. http://crossgl.com/aggpas/documentation/index.html Both options have no dependencies on graphics libraries or GUI systems, so is perfect for console of server side rendering.

Re: [fpc-pascal] link.res search dirs when cross compiling [solved]
Some are hardcoded, and fpc.cfg might contain -Fl lines with paths too
from parsing ld.so.conf on install
Well, I did not put them in ~/.fpc.cfg
In /etc/fpc.cfg there is
-Fl/usr/lib/gcc/x86_64-linux-gnu/10
-Fl/usr/lib/x86_64-linux-gnu/fpc/$fpcversion/lib/$FPCTARGET
-Fl/usr/lib/$fpctarget-*
The last one explains it. I actually have a directory
/usr/lib/'${DEB_HOST_MULTIARCH}'. Why would Ubuntu even ship such a
directory.
$ dpkg -S DEB_HOST_MULTIARCH
libnss3:i386, libnss3:amd64:
/usr/lib/${DEB_HOST_MULTIARCH}/libfreeblpriv3.chk
libnss3:i386, libnss3:amd64:
/usr/lib/${DEB_HOST_MULTIARCH}/libfreeblpriv3.so
libnss3:i386, libnss3:amd64: /usr/lib/${DEB_HOST_MULTIARCH}/libfreebl3.chk
libnss3:i386, libnss3:amd64: /usr/lib/${DEB_HOST_MULTIARCH}/libfreebl3.so
libnss3:i386, libnss3:amd64: /usr/lib/${DEB_HOST_MULTIARCH}

Re: [fpc-pascal] link.res search dirs when cross compiling
How are you specifying your cross-compilation sysroot? Make sure you use the -XR parameter for that, I use -Fl in ~/.fpc.cfg... When I use -XR nothing happens. The link.res is the same, except -Fl prepends the path to link.res and -XR just ignores it. (same for -Xr) Benito ___ fpc-pascal maillist - fpc-pascal@lists.freepascal.org https://lists.freepascal.org/cgi-bin/mailman/listinfo/fpc-pascal

Make sure you use the -XR parameter for that, and not -Fl or so. -Fl just instructs the compiler/linker to add a directory to the list of standard directories to search, rather than to completely ignore your host system and only look for libraries in the hierarchy below the sysroot.

[fpc-pascal] link.res search dirs when cross compiling
Hi,
where do the SEARCH_DIRs in link.res come from?
My build has started failing, after trying it on a new computer with
"/home/benito/bin/arm-linux-androideabi-ld.bfd:android/libs/armeabi/link42815.res:17:
ignoring invalid character `'' in expression"
link.res starts with:
SEARCH_DIR(/home/benito/opt/android/sdk/ndk-bundle/platforms/android-21/arch-arm/usr/lib/)
SEARCH_DIR(/usr/lib/thunderbird-addons/)
SEARCH_DIR(/usr/lib/modules/)
SEARCH_DIR(/usr/lib/aspell/)
SEARCH_DIR(/usr/lib/gnome-shell/)
SEARCH_DIR(/usr/lib/binfmt-support/)
SEARCH_DIR(/usr/lib/udev/)
SEARCH_DIR(/usr/lib/gcc/)
SEARCH_DIR(/usr/lib/cups/)
SEARCH_DIR(/usr/lib/tmpfiles.d/)
SEARCH_DIR(/usr/lib/firewalld/)
SEARCH_DIR(/usr/lib/X11/)
SEARCH_DIR(/usr/lib/cmake/)
SEARCH_DIR(/usr/lib/realmd/)
SEARCH_DIR(/usr/lib/klibc/)
SEARCH_DIR(/usr/lib/sasl2/)
SEARCH_DIR('/usr/lib/${DEB_HOST_MULTIARCH}/')
...
I guess '/usr/lib/${DEB_HOST_MULTIARCH}/ is the problem. Why would it
even add such a dir
Benito
