ld: warning future deprecation

[exagonx]

Hello friends, I wanted to bring to your attention that in version 12 of Linux Debian once the FreeBASIC compiler and all its components are installed, this when compiling a file releases a warning of future deprecation, the executables continue to work correctly, you just have to be careful with the updates.

Code: Select all

exagonx@PIIDebian:/PIISVR/test$ fbc hello.bas
ld: warning: hello.o: missing .note.GNU-stack section implies executable stack
ld: NOTE: This behaviour is deprecated and will be removed in a future version of the linker

Hi All

Can you show us your Compiling / Linking options ?

I am using Debian 12 and not getting this warning.

Hi All

Can you show us your Compiling / Linking options ?

Hi, I'm not using any option I just typed "FBC HELLO.BAS" and from the post, that's the screen that comes out.
Ah FBC version 1.10.1, in 1.10.0 nothing appeared

Hi All

If I change to the folder examples and type fbc hello.bas, there is no display output and the executable file hello is created.
Runs correctly.

If I add -v to the line, Iget:

Still no Warning message.??

Hi exagonx
it would help if you would give the binutils version, e.g. ld --version because a lot of distros don't use the latest tools available

[Dinosaur]

Hi All

2.40 for me.

Regards

[srvaldez]

I just fired-up my Kali VM, it has the latest binutils version 2.43
compiling a FB program doesn't give any warnings

Thank you for your suggestion
This is my version 2.40

exagonx, what if you update FreeBasic ?
I suspect that you may be using an older version

I suggest that you build FB-1.20.0 from source and update your FB installation
<edit> why 32-bit and not 64-bit ?

[marcov]

(32-bit is perhaps native backend instead of cgen ?)

<edit>

Ill do it

why 32-bit and not 64-bit ?

Because is a Pentium II 266Mhz ;P

it is a machine for writing and developing performance-optimized code, having little RAM, an old CPU with obsolete architecture I can time the performance and write fast and stable optimized code

CPU - Intel Pentium II 266Mhz
RAM - 384 MB SDRAM 100Mhz
VGA - Intel 740 AGP + Voodoo 3dfx
LAN - Realtek 8132 10/100

Yes they are nice but I only have Windows 2000 Professional, and having to decide whether to install win2k or winxp I preferred xp for better compatibility with some applications, currently I'm trying to use the freebasic screen 14 graphics mode in a minimal version of Linux without having to depend on the X Window libraries
