I am new to Linux and makefiles. I have a makefile which generates .a files.
When I run the makefile, I get the following error. I have no idea from which part of the code, the error occurs.
[oracle#dyl02703app004 erm]# make -f erm_make_ida all

<command line>:1:1: error: macro names must be identifiers

Any suggestions...?
You have a -D flag with no name. Look in your makefile to see what is causing it.

I'm new to Linux & shell and I'm struggling with checking if the compilation is successful.
g++ code.cpp -o code.o 2>error.txt
if [ ! -e error.txt ]
then
do something
else
echo "Failed to compile"
I guess an error file is created even if the compilation is successful. What is the content of the error file when there is no error? I need to change the if condition to check if the compilation is successful.
It's just the order of things. What happens when the shell parses the string g++ code.cpp -o code.o 2>error.txt is:
The shell creates error.txt, truncating the file if that name already exists.
g++ is called with its error output redirected to the new file.
If g++ does not write any data, then the file remains as it was (empty) at the end of step 1.
You probably aren't so much interested in the error file as you are the return value. You probably ought to just do:
if g++ code.cpp -o code; then : do something; done
or even just:
g++ code .cpp -o code && : do something
but if really want to do something else with the errors, you can do:
if g++ code.cpp -o code.o 2> error.txt; then
rm error.txt
: do something
else
echo >&2 Failed to compile code.cpp.\ See "$(pwd)"/error.txt for details.
fi
Make sure you escape at least one of the spaces after the . so that you get 2 spaces after the period (or just quote the whole argument to echo). Although it's become fashionable lately to claim that you only need one space, all of those arguments rely on the use of variable width fonts and any command line tool worth using will be used most often in an environment where fixed width fonts are still dominant. This last point is totally unrelated to your question, but is worth remembering.
I have clone the latest linux source from git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git
And compile this kernel using (make O=/usr/local/kernel).
But when i install the kernel the following error getting,
# make O=/usr/local/kernel modules_install install
make[1]: Entering directory `/usr/local/kernel'
rm: invalid option -- '0'
Try 'rm --help' for more information.
make[1]: *** [_modinst_] Error 1
make: *** [sub-make] Error 2
I faced the same issue today (24/1/20) and after a bit of searching, I decided to remove the # in front of each line in modinst target in Makefile. The problem was immediately visible to me. If you add space in extra version, the space will appear in your folder name. So, if you write extra version as
EXTRAVERSION= -test[un-noticed-space-here]
Your module folder name will also have that space. To avoid it, I tried the following
Made sure that there are no spaces at the end of version lines in Makefile
Did "make kernelversion" and made sure that it is devoid of any space character
Did a
echo -n `make kernelversion`| wc
and reconfirmed above point by comparing wc output and the count of characters from previous step
The code snippet is as follows:
$(shell javac $(MY_PATH)/test/TestFile.java)
$(shell java -cp $(MY_PATH)/test/ TestFile)
There is no space or tab in the start. The error i am getting is
* missing separator. Stop.
The error is coming in second line only and not in the first line.
Basically my TestFile is not in java path.
I have tried all the solutions here but none helped me out. I guess the error has something to do with the directory path I provided. The same code snippet works with cmd prompt in windows but not in linux machine. Can't figure the exact problem. Kindly help. Thanks.
This is how makefiles supposed to be used:
.PHONY: run
JAVAC:=javac
JAVA:=java
TARGET:=TestFile
SOURCES:=TestFile.java
OBJS:=$(patsubst %.java, %.class, $(SOURCES))
$(TARGET): $(OBJS)
%.class: %.java
$(JAVAC) $^
run: $(TARGET)
$(JAVA) $(TARGET)
make run will compile and run. make will only compile. Of course it all could be set to one target, but better don't do that.
I am new in Linux, can anyone tell me which directory the computer search for "ansinist.h"? Below is the syntax:
USER#USER-PC /cygdrive/f/Dataset_extract/500ppi-Legacy/SRC/BIN/TXT2NIST
$ make -f makefile.mak
gcc -ansi -O2 -I/include -L/lib -c txt2nist.c
txt2nist.c:15:22: fatal error: ansinist.h: No such file or directory
#include <ansinist.h>
^
compilation terminated.
makefile.mak:53: recipe for target 'txt2nist.o' failed
make: *** [txt2nist.o] Error 1
This answer could help you. In general case, be sure that you have installed the libraries that you're going to use in your project.
To find the file ansinist.h
sudo find / -name ansinist.h
And please paste your output here but you should be sure you installed all the required libraries first..
1)if your header file is in current directory then use #include "ansinist.h"
because this syntax search directly into current directory.
2)if your header file is in /usr/include/ then #include< ansinist.h>
because this syntax first search into /usr/include/ then current directory.
3)also you can use #include < /path/ansinist.h>
where path=path where is header file.
4)if above things will not work then please give value of #echo $PATH for next i can help you.
Code snippets of makefile:
ERROR_PARSER_YACC = $(SRCDIR)/ermparseyac.y
ERROR_PARSER_LEX = $(SRCDIR)/ermparselex.l
ERM_OBJS = \

The value of SRCDIR is "/home/wholesale/children/dev5/comps/erm/src".
When I run the makefile, I get the following error:
.... Compiling /home/wholesale/children/dev5/comps/erm/obj/ermparselex.c

/pf24/wholesale/dvp/comps/erm/src/ermparselex.l:168: error: previous implicit declaration of âget_comment_lineâ was here
I don't understand how makefile is replacing the location "/home/wholesale/children/dev5/comps/erm/src" to a different location "/pf24/wholesale/dvp/comps/erm/src/" which is not present in the sever.
You seem to be confusing make output with your compiler output. The error messages you showed are not produced by make, but by whatever compiler (probably gcc) you're using.
Note that the assignemt to ERROR_PARSER_LEX is a deffered assignment. The value of SRCDIR is expanded whenever ERROR_PARSER_LEX is used. That might explain why the value of SRCDIR doesn't appear to be what you think it should be.
Edit
The problem doesn't appear to be related to your makefile. Make clearly shows that it's passed /home/wholesale/children/dev5/comps/erm/src/ermparselex.c to the compiler as source file.
The error message which points to a different file probably means that some source file is including something from /pf24.
The -E option of gcc can be quite useful in diagnosing such issues. Replace the -o ... options by it, and it'll output the preprocessed source code to stdout. This should show you which file is including the file in /pf24.
