1. WANTED: Experience in developing large commercial applications on linux
currently I'm looking for people that either ported a commercial product
to linux already or are doing that right now.
This is because I would like to have information about problems that
are specific to this OS. And of course I don`t want to reinvent the wheel...
So, I'm interested in portings of applications with properties as below:
- Motif2.0 based
- high end 3D graphics support
- 2 Million+ 3D-polygons per second
- 2 X 8 bit (double buffering): at least
- 12 bit double buffering, hardware Z-buffer, Gouraud shading: recommended
- 24 bit " " " : a good choice
- code mixture of C++, C, LISP
- reimplementations of malloc and free (new and delete)
- free will never give memory back to the OS
- malloc will reuse it later
- 2 Millions lines of code
- 32000 files in 6000 directories
- sophisticated development (ksh) tools to
- enable access to SCCS/RCS for 100+ developers
- set up hardware independant development environments
- generate Makefiles automatically
- support distributed compilation in workstation clusters
- support incremental linking
- multi language support (multi byte characters)
- us english, german, french, italian, japanese: kanji (!)
- binary size (of the PA/RISC executable):
a) debug version 74 MByte
b) NON debug version 32 MByte
- RAM required (NON debug version):
48 MB to start it up
128 MB to work with it
256 MB make sense, the more the better ...
- swap space required (NON debug version):
50 MB to start it up
300 MB recommended
1 GB ok, the more the better ...
If you have experience with a system like this, please send an email
directly to me.
Especially I'm interested in
a) system call compatibility (e.g sbreak),
b) compiler bugs,
c) ksh <-> bash compatibility,
d) nmake performance with deeply nested directory structures,
e) more general information about how the OS's reliability will be
if there is a high swap load and much traffic on the net.
How often occur FS crashes and how reliable deals fsck with them?
Can I have mirror disks to reduce the risk of disk crashes?
Does linux support VFS? e.g. can I define a file system with
2 GB if I have a 1 GB disk and two 500 MB disks?
Thanks in advance for any comment,
