Here is my code of Header File.
Header File name 16f877a.h
its code get from this link
My File name led.c
#include "16f877a.h" //IC selection
#fuses XT, NOWDT, NOPROTECT, NOLVP
#use delay (clock =20000000) //clock 20MHz
void main(){
while(1){
output_B(0xff); //hex to binary output on port B
delay_us(500); // delay = 500 x clock period.
output_B(0x00);
delay_us(500);
}
}
those files are located in same folder
/home/company/Documents/CCPP/PIC/LedProject
I use UBUNTU 12.04.
with gcc I compiled a simple hello world program and its runs correctly.
here is my command history in terminal
mkdir -p PIC/LedProject
cd PIC/LedProject/
gedit led.c
gcc -Wall -W -Werror led.c -o LedProC
and here is my error.please help me to sort this issue

I refer this blog for my circuit
You are using source code that is not strictly C but an extension that includes many preprocessor commands like
#fuses XT, NOWDT, NOPROTECT, NOLVP
#use delay (clock =20000000) //clock 20MHz
These are use to configure a PIC processor. The complier for this C like language has a built in understanding of functions like
delay_us()
The compliant C compiler (gcc) you used has no understand of fuse, delay_us , etc. and so declares a host of errors.
If you goal is to program a PIC - which I think it is, using this type of C, go to MicroChip, CCS, or elsewhere and get their PIC C compiler.
If you goal is to program with your gcc on your UBUNTU machine, do not use code designed for PICs.
BTW: There may exist cross-compilers for PIC that compile on your UBUNTU, but I am not aware.
Search the questions for gcc PIC cross-compiler and you may find it answered.

I'm trying to build a BPF program written in C into the bpf bytecode. The program C code was taken from https://github.com/iovisor/bcc/blob/master/tools/bindsnoop.py (I used C code from bpf_text with some customizations).
I didn't want to use bcc python tools, my purpose is to write both kernel and user space code in C, and I would like to build a kernel program outside of the kernel tree.
I use Ubuntu 20.10 and here is uname -a output:
Linux bb-VirtualBox 5.8.0-63-generic #71-Ubuntu SMP Tue Jul 13 15:59:12 UTC 2021 x86_64 x86_64 x86_64 GNU/Linux
Linux headers are installed, but for some reason I have two directories containing linux headers for 5.8.0-63:
/usr/src/linux-headers-5.8.0-63
and
/usr/src/linux-headers-5.8.0-63-generic
I used this post to create a makefile for my program: https://blogs.oracle.com/linux/post/bpf-in-depth-building-bpf-programs
so the makefile looks like below:
OBJS = kprobe_bindsnoop_kern.o
LLC ?= llc
CLANG ?= clang
INC_FLAGS = -nostdinc -isystem `$(CLANG) -print-file-name=include`
EXTRA_CFLAGS ?= -O2 -emit-llvm
linuxhdrsgen ?= /usr/src/linux-headers-5.8.0-63-generic
LINUXINCLUDE = -I$(linuxhdrsgen)/arch/x86/include \
-I$(linuxhdrsgen)/arch/x86/include/generated/uapi \
-I$(linuxhdrsgen)/arch/x86/include/generated \
-I$(linuxhdrsgen)/arch/x86/include/uapi \
-I$(linuxhdrsgen)/arch/x86/include/generated/uapi \
-I$(linuxhdrsgen)/include/uapi \
-I$(linuxhdrsgen)/include/generated/uapi \
-I$(linuxhdrsgen)/include \
-include ${linuxhdrsgen}/include/linux/kconfig.h
all: $(OBJS)
.PHONY: clean
clean:
rm -f $(OBJS)
INC_FLAGS = -nostdinc -isystem `$(CLANG) -print-file-name=include`
$(OBJS): %.o:%.c
$(CLANG) $(INC_FLAGS) \
-D__KERNEL__ -D__ASM_SYSREG_H \
-Wno-unused-value -Wno-pointer-sign \
-Wno-compare-distinct-pointer-types \
-Wno-gnu-variable-sized-type-not-at-end \
-Wno-address-of-packed-member -Wno-tautological-compare \
-Wno-unknown-warning-option \
-I../include $(LINUXINCLUDE) \
$(EXTRA_CFLAGS) -c $< -o -| $(LLC) -march=bpf -filetype=obj -o $#
And kprobe_bindsnoop_kern.c starts from the following set of include files:
#include <uapi/linux/ptrace.h>
#pragma clang diagnostic push
#pragma clang diagnostic ignored "-Wtautological-compare"
#include <net/sock.h>
#pragma clang diagnostic pop
#include <net/inet_sock.h>
#include <net/net_namespace.h>
#include <bcc/proto.h>
Below you can see the compilation output:
clang -nostdinc -isystem `clang -print-file-name=include` \
-D__KERNEL__ -D__ASM_SYSREG_H \
-Wno-unused-value -Wno-pointer-sign \
-Wno-compare-distinct-pointer-types \

fatal error: too many errors emitted, stopping now [-ferror-limit=]
20 errors generated.
I tried to add
#include <linux/types.h> or
#include <asm/types.h>
but it doesn't help.
I checked many posts, like this
Error compiling eBPF C code out of kernel tree
and this
how to build BPF program out of the kernel tree
but still failed to get answer.
What am I missing?
Any help will be greatly appreciated ))
Thanks to everyone who tried to help me!
Finally the issue was sooooo simple - just needed to change an order of the include directories specified in the makefile.
Just moved "-I$(linuxhdrsgen)/include" to be the first in the list and it solved the issue.
Meaning, now the list of include dirs looks as follows:
LINUXINCLUDE = -I$(linuxhdrsgen)/include
-I$(linuxhdrsgen)/arch/x86/include
-I$(linuxhdrsgen)/arch/x86/include/generated/uapi
-I$(linuxhdrsgen)/arch/x86/include/generated
-I$(linuxhdrsgen)/arch/x86/include/uapi
-I$(linuxhdrsgen)/arch/x86/include/generated/uapi
-I$(linuxhdrsgen)/include/uapi
-I$(linuxhdrsgen)/include/generated/uapi
-include ${linuxhdrsgen}/include/linux/kconfig.h

cc1: all warnings being treated as errors
In addition, if I add -march=native,avx512f or -mavx512f or -march=skylake-avx512, it gives the following error:
src/main.c:1:0: error: bad value (skylake-avx512) for -march= switch
My GCC version is 4.8.5 20150623 and CPU is "Intel(R) Xeon(R) Gold 6154". What should I do to overcome this problem? Thanks in advance..
GCC 4.8 does not support any of the AVX-512 variants. If this is the system compiler from Red Hat Enterprise Linux 7, you can use a new GCC version from Red Hat Developer Toolset, which provides support for later CPU features. (DTS is also available for CentOS.)
I'm trying to compile source code, that from 2001, in Ubuntu 18.04.2 LTS. But, I got the errors below and actually don't know how I have to change the compiling code. Can you help me for compiling this code?
Suggested compilation part from the program
SUGGESTED COMPILATION COMMAND LINE (FOR A DEC-ALPHA CC-COMPILER):
cc -lm -fast -tune host -arch host -assume whole_program \
-o mol_volume mol_volume.c
When I tried this code, errors;
cc: error: host: No such file or directory
cc: error: host: No such file or directory
cc: error: whole_program: No such file or directory
cc: error: unrecognized command line option ‘-fast’; did you mean ‘-Ofast’?
cc: error: unrecognized command line option ‘-tune’; did you mean ‘-mtune=’?
cc: error: unrecognized command line option ‘-arch’; did you mean ‘-march=’?
cc: error: unrecognized command line option ‘-assume’; did you mean ‘-msse’?
Then, I changed -fast, -tune, -arch, -assume flags with -Ofast, -mtune=native, -march=native, -msse then add the path the for the directory part of the errors.
cc -lm -Ofast -mtune=native -march=native -msse /mypath/ -o mol_volume mol_volume.c
Then, I got that error;
mol_volume.c: In function ‘main’:

gets was removed in C11. Compile with gcc -o mol_volume -Wall -std=c99 -mtune=native -O3 mol_volume.c -lm.
It will work but you should fix the code to remove all the warnings.
io.cuh:

I'm trying to compile simple program using the following makefile:
lodepng.o: lodepng.h
cc -c lodepng.c -o lodepng.o
io.o: io.cuh lodepng.o
nvcc -c io.cu -o io.o
main: io.o
nvcc main.c io.o -o main
'main.c' uses one function from io.cu, which is dependent on lodepng.c.
After some minor warnings that reference to the code, I got the following error:
nvcc main.c io.o -o main nvcc warning : The 'compute_10' and 'sm_10'
architectures are deprecated, and may be removed in a future release.
In file included from main.c:1:0: io.cuh:12:12: error: expected ‘=’,
‘,’, ‘;’, ‘asm’ or ‘attribute’ before ‘void’ global void
transformToGrayKernel(rgb_image *img);
^ makefile:6: recipe for target 'main' failed make: *** [main] Error 1
The error is caused by the key word __global__, not your kernel's prototype.
That's because the compiler nvcc will interpret its input file, and choose the corresponding rule to compile it. Although you use the nvcc to compile the "main.c", but it will be treated as a C source file, not a CUDA source code. So the compiler can not recognize the CUDA key word __global__ when it compile the file "main.c".
You can change the file type from "main.c" to "main.cu", and it will be treated as a CUDA source code. Then the compiler can recognize the key word __global__.
I've downloaded ximpleware_2.11_c.zip (C version of vtd-xml), when I
have tried to compile it under linux I've the following error messages:

How can I build it under linux ?
Thanks for your response.
I've put
#include <stdio.h>
in :
vtdNav.h and in transcoder.h
and now it compile.
I'm sorry to have put a post to ask how to compile the examples. I have compiled them by modifying the makefile already present in ximpleware_2.11_c and in this way works:
