I'm trying to compile a simple little test program. and I'm getting errors:
MacBook-Air:Untitled user$ ls
main.c makefile utils.c utils.h
MacBook-Air:Untitled user$ make
avr-gcc -I. -g -mmcu=atmega640 -Os -fpack-struct -fshort-enums -funsigned-bitfields -funsigned-char -Wall -Wstrict-prototypes -Wa,-ahlms=main.lst -c main.c -o main.o
make: avr-gcc: No such file or directory
make: *** [main.o] Error 1
MacBook-Air:Untitled user$
What file is gcc complaining about? main.c does exist in the same directory as the makefile so I'm confused.
It's not the C file it can't find, it's the C compiler (avr-gcc). Is it defined in the makefile? E.g. CC=avr-gcc ? You could try replacing that with CC=gcc

I'm trying to link a static library archive file (libx/libx.a) with a C code. The library requires 2 flags (-lx -lpthread). After linking the static library my ultimate goal is to create a shared library. I have the following Make file,
rsa-engine: rsa/rsa.c rsa/bignum.c rsa/aes.c rsa/x509parse.c rsa/pem.c
gcc -fPIC -o rsa/rsa.o -c rsa/rsa.c
gcc -fPIC -o rsa/bignum.o -c rsa/bignum.c
gcc -fPIC -o rsa/aes.o -c rsa/aes.c
gcc -fPIC -o rsa/x509parse.o -c rsa/x509parse.c
gcc -fPIC -o rsa/pem.o -c rsa/pem.c
gcc -fPIC rsa-engine.c libx/libx.a -L.libx/ -lx -lpthread -o rsa-engine.o
gcc -shared -o librsa_engine.so -lcrypto rsa-engine.o rsa/rsa.o rsa/bignum.o rsa/aes.o rsa/x509parse.o rsa/pem.o
clean:
rm -f *.o rsa/*.o *.so rsa-engine
After using the make command it produces the following output,
/usr/bin/ld: cannot find -lx
collect2: error: ld returned 1 exit status
Makefile:2: recipe for target 'rsa-engine' failed
make: *** [rsa-engine] Error 1
I found similar questions here. But that did not help. Seems like I can't make the link work. Any help with what I'm doing wrong?
I would like to achieve the same result generated by the following command,
CC := gcc
CFLAGS := -Wall -g -MD -O2 -I ../
LDFLAGS := -lx -lpthread
tests_files := hello
all: $(tests_files)
hello: hello.o ../libx/libx.a
$(CC) $(CFLAGS) -static $(<) -L../libx/ $(LDFLAGS) -o $(#)
It seems that your libx.a is located in libx, yet -L references .libx directory. Anyway, since you reference libx/libx.a directly, you may skip both -L.libx/ -lx and it should link just fine.
when running a makefile, which includes a usage of
a script-file, I receive an error saying the linker doesn't find the script file.
When running the make file the output is as follows:
arm-none-eabi-gcc -g -Wall -Werror -c -o main.o main.c
arm-none-eabi-gcc -g -Wall -Werror -c -o misc.o misc.c
arm-none-eabi-gcc main.o misc.o misc.h -g -Wall -Werror -Wl,-Map=HOST.map -T=msp432p401r.lds -o HOST
/usr/lib/gcc/arm-none-eabi/9.2.1/../../../arm-none-eabi/bin/ld: cannot open linker script file =msp432p401r.lds: No such file or directory
collect2: error: ld returned 1 exit status
make: *** [Makefile:11: HOST] Error 1
The makefile content is:
#---- Variables (machine depending) --------
TARGET = HOST
CC = arm-none-eabi-gcc #gcc
CFLAGS = -g -Wall -Werror # compiler flags
LDFLAGS = -Wl,-Map=$(TARGET).map -T=msp432p401r.lds # linker flag
SOURCE = main.c misc.c misc.h
OBJS = $(SOURCE:.c=.o) # replace all c with o
#---- Targets -----------
$(TARGET): $(OBJS)
$(CC) $(OBJS) $(CFLAGS) $(LDFLAGS) -o $#
I have searched a lot for a solution for this issue, and tried various fixes, with no success.
The script file is located at the same location as the source files.
What can be the reason for not finding the file?
Thanks
I am getting the following error when I try to build gcc 8.2.0 on OpenBSD 6.3:

My process:
Install OpenBSD (using defaults)
Run syspatch
Add some packages:
# pkg_add wget
# pkg_add gmp mpfr libmpc
# pkg_add gmake
Get the source:
$ wget ftp://ftp.nluug.nl/mirror/languages/gcc/releases/gcc-8.2.0/gcc-8.2.0.tar.gz
$ tar xzf gcc-8.2.0.tar.gz
$ cd gcc-8.2.0
Build:
$ ./configure --prefix=/opt/gcc-8.2.0 --with-gmp=/usr/local --enable-languages=c,c++
$ gmake
This also fails with gcc 8.1.0 in a similar way.
I also tried using clang rather than gcc to build, like this:
$ CC=cc CXX=c++ ./configure --prefix=/opt/gcc-8.2.0 --with-gmp=/usr/local --enable-languages=c,c++
That made no difference, which makes some sense as apparently it is failing in stage 3 (gcc compiling itself again for a final check).
Annoyingly, there is a stdatomic.h file in the tarball:
$ find gcc-8.2.0 -name stdatomic.h
gcc-8.2.0/gcc/ginclude/stdatomic.h
So I have no idea what I am missing.
Has anyone successfully built this? How?
For compatibility/legacy reasons I need to build the Lua compiler (luac) from version 5.0, on my 64bit Intel Mac. (5.1 or later can't be used.)
Dev tools installed through Xcode 4.6's Preferences window.
After I 'cd' in to the Lua directory, I issue the command 'make'.
cd include; make all
make[1]: Nothing to be done for `all'.
cd src; make all
make[1]: Nothing to be done for `all'.
cd src/lib; make all
make[1]: Nothing to be done for `all'.
cd src/luac; make all
gcc -o ../../bin/luac luac.o print.o lopcodes.o -L../../lib -llua -llualib -lm
Undefined symbols for architecture x86_64:
"_UNUSED", referenced from:
_writer in luac.o
ld: symbol(s) not found for architecture x86_64
collect2: ld returned 1 exit status
make[1]: *** [../../bin/luac] Error 1
make: *** [all] Error 2
I do not know how to configure the make process for x86_64. Could someone please step me through it?
Thanks.
It works for me, but the output below is different from yours:
...
cd src/luac; make all
gcc -O2 -Wall -I../../include -I.. -c -o luac.o luac.c
gcc -O2 -Wall -I../../include -I.. -c -o print.o print.c

gcc -o ../../bin/luac luac.o print.o lopcodes.o -L../../lib -llua -llualib -lm
cd src/lua; make all
gcc -O2 -Wall -I../../include -c -o lua.o lua.c
Try make clean all at the top level first.

Can some one help me out on this ?
I have the same problem that I worked for a whole day!! I have a hit, as least this bug disappeared.
When it refers to GLIBCXX_3.4.15 it means that you are using a g++ or gcc with the library not providing the functions or classes you need, very likely 4.4 or 4.5. I changed my g++ and gcc to 4.6 and the problem was solved. For some references, you can check out the following:
How standard lib linked by libstdc++.so.6
Notice: I only get libstdc++.so.5 in /usr/lib when I have g++-4.5 installed. I think libstdc++ is the library that g++ and gcc used.
for changing the compiler version in Linux, see the following link:
Upgrade your compiler
Hope it helps!
