gcc-10: options order important?
Hi,
in contrary to previous versions, now in Debian 11 with gcc-10:
gcc aa.c -lm -o aa works, but
gcc -lm aa.c -o aa does not work, saying:
/usr/bin/ld: /tmp/ccWyhudO.o: in function `main':
aa.c:(.text+0x1f): undefined reference to `sqrt'
collect2: error: ld returned 1 exit status
My aa.c content:
---
#include
#include
int main(void)
{
double x=4;
printf("sqrt(4)=%f\n",sqrt(x));
return 0;
}
---
It seems that an option -lm cannot be placed in an arbitrary place which I used
to
do. Is this intentional ?
Regards,
Piotr A. Dybczyński

Re: Debian 11 doesn't suspend properly on Acer Aspire 5 A515-51G-52GM
Hi, I have similar problem on Dell Inspiron 3580 Both after upgrade from Buster to Bullseye and after clean install on a seprate partition laptop does not wake up (in fact it sometimes does) but completely freezes, only power off can help. When I booted Bullseye with the previous kernel (4.19) it works OK. My hardware is (from lspci): 00:02.0 VGA compatible controller: Intel Corporation WhiskeyLake-U GT2 [UHD Graphics 620] 01:00.0 Display controller: Advanced Micro Devices, Inc.

impossible to apply security updates
It seems something is going wrong with DNS. security.debian.org points to 0.0.0.0 !! Regards Piotr -- / Dr Piotr A.

AIDE problem
Sorry for repeating my question, but my previous posting became erroneously attributed as the reply to some other one. My problem: I have noticed a strange behaviour if the AIDE filesystem integrity checker. Lately I got a new computer (dual Xeon 3 GHz) and installed Woody with some standard software I used to install for years - AIDE among others. But AIDE generates (randomly, almost everyday) false reports about changed files. It says that one, or hundred files changed, namely that MD5 and SHA1 checksums are different: File: /usr/lib/itk3.1/itk.tcl MD5 : a4X16bduSkXdKpMeKK2nOw== , eWxasPaShK0y8mx/LNlemA== SHA1 : 9MeC2Em8xJ9j1aA5dcYo/VCEAxk= , OlfwA1KnHRC/WxcYii4ng4hAwKo= But files are unchanged! Next run of AIDE with the same database gives different warnings or says no differences. I am using the same AIDE v0.8 from *.deb on single cpu machine and it works well. I have tried to rebuild *.deb, to compile with Intel icc compiler but nothing helps. On single cpu machine it works on dual not. Any suggestions? -- / Dr Piotr A.

problem with AIDE
Hello everybody, I have noticed a strange behaviour if the AIDE filesystem integrity checker.
