RaspberryBASIC.org Forum

I just read a thread on the RPi forum on how to make Rasbian run as a 64 bit OS. Seems to be having a lot of issues getting standard tools to run unlike the Ubuntu 64 solution.

John, 64-bit 8th binary for string and array challenge is available here

[John]

Can you post the source as well?

[John]

AIR,

I've hit the wall trying to get IUP compiled from source on Ubuntu 64 RPi 4B. This is a critical tool for both Nim and embedded ScriptBasic efforts.

From what I can tell from the errors I'm getting, IUP make is having a problem determining the Linux platform, endian class and glib version..it's like if fell through its selection tree and trying to compile half baked.

Interestingly, the arch is "aarch64".

Can you take a look?

GO generating over a 2 meg executable seem excessive for a program this small.

8th still holds the crown at 8 megs.

What I gained from these rounds of language comparisons is Nim, Swift and PHP is going to get a lot more of my attention.

Both include their runtimes, etc in the final executable.

Statically linking the C submission:

Code: C

1. gcc -static mil.c $(pkg-config --libs --cflags glib-2.0) -lpthread -o mil64_s

Results in a binary that is 2.3MB in size.

For GO, try this:

Code: Go

1. go build -ldflags="-s -w" mil64.go

On my raspi, I get a binary that is 1.4MB in size.

Are you using 'tecmake' to regenerate the makefile?

tecmake functions essentially the same as "./configure" does.  If you look at the tecmake.mak file, you'll see:

Code: GNU make

1.   ifneq ($(findstring aarch64, $(TEC_SYSARCH)), )
2.     TEC_SYSARCH:=arm64
3.   endif
4.  

It will also set the proper endianness for you, but there is something you need to be aware of:

Code: GNU make

1. ifeq ($(TEC_SYSARCH), arm64)
2.       # Our dynamic library build is not working in arm64
3.       NO_DYNAMIC ?= Yes
4.       BUILD_64=Yes
5.       TEC_UNAME:=$(TEC_UNAME)_arm64
6. endif

Best guess is that only static libs will be built, if so your binaries will (ironically) be larger.

This is what I get when I try to make tecmake.mak.


ubuntu@rpi4b:~/iup-dev/lua53/src$ make -f tecmake.mak

You need to use TECMAKE

[John]

Can explain what you mean by use TECMAKE?

[AIR]

Is it configured for your system as the docs at that link specify?

[John]

I downloaded the TECMAKE zip and tried to use it and I get an error saying -f is missing.  I have spent hours on this and getting nowhere,

Can you try to build it on your end and send me a zip of the binaries.

I had no problems compiling this on Rasbain 32.

[AIR]

NO, I don't do gui on my pi's...

I think the first issue is at around line 624 in the .mak file:

Code: GNU make

1.     ifeq ($(TEC_SYSARCH), ia64)
2.       STDFLAGS += -fPIC
3.       X11_LIB := /usr/X11R6/lib
4.     else
5.       STDFLAGS += -m64 -fPIC
6.       X11_LIB := /usr/X11R6/lib64
7.     endif
8.   else
9.     X11_LIB := /usr/X11R6/lib
10.   endif
11.   X11_INC := /usr/X11R6/include
12.   MOTIFGL_LIB :=
13.   ifdef USE_OPENMP
14.     STDFLAGS += -fopenmp
15.     LIBS += gomp
16.   endif
17. endif
18.  

There is no check for 'arm64' in that block, so it defaults to setting STDFLAGS to "-m64 -fpic" in line '5' above.

You can either add/fix that yourself, or file a bug report.

Removing the -m64 allowed me to compile Lua, IM. CD and IUP are still hosed. This is a major show stopper for me with Ubuntu 64 on the RPi.
