Here is a step-by-step guide to troubleshoot the “pcre.h” file not found error and build VanityGen:

1. Step 2: Check the installation of required libraries

Make sure you have installed the following libraries required by VanityGen:

  • libpcre-8-dev (Ubuntu-based systems): sudo apt-get install libpcre-8-dev
  • libpcre3-dev (non-Ubuntu systems): sudo yum install pcre3-devel

2. Step 2: Update your compilation flags

You need to add the following flag in your build file to enable the “-fstack-protector” optimization:

  • -Wall -Wextra -Werror in your .sh file
  • -O3 and fstack-protector with the -static flag for non-Ubuntu-based systems: sudo make -j$(nproc) CFLAGS="-fstack-protector -static"
  • For Ubuntu-based systems, you can use the following command in your .sh file:

sudo make -j$(nproc) CFLAGS=-fstack-protector -static

3. Step 2: Compile VanityGen

After updating the compiler flags, try compiling VanityGen again. Here is a sample "Makefile" that you can use as a starting point:

CC = gcc

CFLAGS = -Wall -Wextra -Error -fstack-protector -static

LDFLAGS = -static

sample.o: sample.c

$(CC) $(CFLAGS) -c sample.c

sample: sample.o

$(CC) $(LDFLAGS) -o sample ./sample.o

install:

sudo make install

4. Step 2: Run the build command

Now run the following command to compile VanityGen:

prepare

This should compile VanityGen successfully. If you encounter any problems or errors, please check the error messages in the “Makefile” for more information.

Hope this helps! If you have any further questions or concerns, please let us know.
