I'm getting this compilation error:
fatal error: can’t create precompiled header f: Text file busy
compilation terminated.
This is a very mysterious one, since i get it only once in a while..
Where do i go wrong?
ETXTBSY is a standard errno value, the best explanation I've found being:
An attempt to execute a file that is currently open for writing, or write to a file that is currently being executed. Often using a debugger to run a program is considered having it open for writing and will cause this error. (The name stands for "text file busy".)
So, you might still be executing the program the compiler is trying to recreate/update...?

I'm using Embarcadero C++ Builder 10.1 Berlin Update 2.
I added one file to a project. I tried to build said project and the build failed and reported the following error:
[bcc32 Fatal Error] FileName.cpp(44329): F1008 Out of memory
I have been reading up on errors that can be found via Google and am only finding linker errors. My understanding is that this isn't a linker error as I'm not seeing [ilink32]. I haven't come across any examples of this error.
The file I added has 25 lines in the h file and 64865 lines in the cpp file. The following method takes up 64755 lines of the cpp file.
void __fastcall TFileName::PopulateKeyValueList()
{
SOKeyValueList->Clear();
SOKeyValueList->AddPair("AKey","AValue");
... roughly 64750 more lines like the one above adding pairs to the list
}
This wasn't an issue before I added the file containing 65k lines of code to the project so I believe the appropriate question is, how may I resolve a file containing 65k lines of code causing a [bss32 Fatal Error] F1008 Out of memory error?
It’s generally not a good idea to hard code data (especially so much data in your case) into a source file. You should put key-value pair info in a file and read them out to build the key-value list.
For the error, I guess the compiler you used is just not good enough to handle large source files.
I have two short files located in the same directory. The contents of each are shown below.
File test.cpp contains:
int main()
{
#include <test.h>
}
File test.h contains:
syntax_error
Upon compiling test.cpp with either g++ or clang++, I get an error which is expected.
test.cpp:3:11: error: 'test.h' file not found with <angled> include; use
"quotes" instead
#include <test.h>
^~~~~~~~
"test.h"
However, I also get a second error which seems to contradict the first error.
In file included from test.cpp:3:
./test.h:1:1: error: use of undeclared identifier 'syntax_error'
syntax_error
^
Essentially, the first error reports that the compiler cannot find the file test.h, and the second reports a syntax error in the file that the compiler reported it could not find.
These are the only two errors generated.
I understand why the compiler reports the first error and that I should use quotes with #include in this case. Why, though, does the compiler say it cannot find the file when it clearly has found it? And, why would it continue to report errors in the "unfound" file?
This is a feature, not a bug.
The idea is that if the error is trivial (like a missing semicolon), then the compiler will try to continue compiling as if you had already fixed the error. This enables you to fix multiple errors in one go. This is especially useful when compiling your code takes a long time.
Imagine fixing a missing semicolon, recompiling for five hours, just so that the compiler finds another missing semicolon. And then you have to recompile again. That would be very frustrating, no?
Basically, the compiler will try to recover from any errors as far as it is able to, to be able to report as much errors as possible. Most compilers have a flag for this.
Why, though, does the compiler say it cannot find the file when it clearly has found it?
The compiler found the file yes, that's why it gave you a hint to use "" instead of <>. If it hadn't, it might not have given you the hint. Still, the compiler is not allowed to compile your code correctly, because your code is ill-formed.
As an analogy, just because the compiler found a missing semicolon, that doesn't mean that it can just compile the code with that missing character (if it tries to be Standards compliant). It will however recover and try to find other errors, if any.
I have a program with many files and right now I have a huge bunch of compiler errors which I have a hard time understanding. The only line references I get are references to C++ libraries, such as algorithm or utility.
My question is: how am I supposed to know where the compiler error is? Some line in my code obviously generated an error in a C++ library, but where was it generated? Is there any way to get more info about the compiler errors? It's not like I can debug it, since it's in compile time.
EDIT: I realize this could be difficult to understand. Here are some examples of errors which I have modified for simplicity reasons.
(1) Here the error is on a line which includes std::string and I have no idea where it tries to do something with ClassY.
In file included from [my path]/ClassX.cpp:1:
In file included from [my path]/ClassX.h:4:
In file included from /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/../include/c++/v1/string:439:
/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/../include/c++/v1/algorithm:2123:24:
error: invalid operands to binary expression ('my project::ClassY *' and 'const my project::ClassY')
EDIT 2: problem solved. There were in total 31 error lines and note lines. I thought these had nothing to do with the above. However, they were all connected to one single line, which was referenced further down in the error messages:
myvec.erase(std::remove(myvec.begin(), myvec.end(), item), myvec.end());
How to fix the above error ? I am trying to build my code on IAR embedded workbench through makefile. While building, it throws the above error.
I think more details need to be specified. If you can paste the full error you got when compiling the code, that will help. Also compiling error must be referring to some source file with a specified line number also....It will be helpful if you can paste the snippet around the line of error from the source file.
I am compiling a fortran code using gfortran, it is giving me an error stating
2.6/cp2k/tools/build_libsmm/run_tiny_dnn/output_linux.gnu/"//trim(filename)
1
Error: Syntax error in OPEN statement at (1)
I am not sure what could have triggered this. BTW, there was no issue with ifort and the line that triggered is
open(unit=unit,file=\"`pwd -P`/$(OUTDIR)/\"//trim(filename))
It would be great, if someone has any pointers to fix this issue.
The open() statement in fortran needs the relative path to the file to open from the position of where the compiled fortran program will resort. So your code should look similar to this with dir the relative path to your output files.
! parameter declaration
integer,intent(in)::unit
char(len=512),intent(in)::dir,filename
char(len=512)::relPath
! -----------------------------------------------------------------------
relPath=trim(dir)//'/'//trim(filename)
open(unit=unit,file=trim(relPath),action='readwrite',possition='append')
I always add the action and position to the open command to make sure that you do the right things with your files.
